Ammonia is formed in the Haber process according to the following balanced equation N 2 3H 2 2NH 3 ΔH -924 kJmol The table shows the percentages of ammonia present at equilibrium under different conditions of temperature T and pressure P when hydrogen and nitrogen gases were mixed in a 31 molar ratio. 4 The concentrations of the products and reactants are constant.

As the reaction proceeds toward equilibrium the color of the mixture darkens due to the increasing concentration of NO 2. Chemistry questions and answers. The concentration of products and reactants are equal.

The extent of a reaction 2. The following graph describes the reaction. Essentially when in chemical equilibrium substances becomes definite and constant.

When the chemical reaction a b c d is at equilibrium which of the following is true. The reaction is now irreversible. The following reaction reaches equilibrium at the specified conditions.

1 The products are completely consumed in the reaction. The system is closed and all reactants and products are present. So remember that when a reaction is in chemical equilibrium that means that the concentrations of the reactant and products remained stable.

Q c is larger than K c. A mixture of NO g and Cl 2 g is placed in a previously evacuated container and allowed to reach equilibrium according to the chemical equation shown above. But in a reversible reaction the products can react to produce the original reactants.

The concentrations of products and reactions are equal Be the reaction is now irreversible. Which of the following can we predict from an equilibrium constant for a reaction. All of the reactants are consumed.

When the system reaches equilibrium the reactants and products have the concentrations listed in the table. Both forward and reverse reactions have halted. Colorless N 2 O 4 reacts to form brown NO 2.

All of the products are consumed. Which of the following statements correctly describes any chemical reaction that has reached equilibrium. A mixture of NO 2 and N 2 O 4 moves toward equilibrium.

Q c is equal to K c. When the system reaches equilibrium both N 2 O 4 and NO 2 are present. If this is true then the reaction is at equilibrium.

Cl2g 2018 This reaction reaches equilibrium at and the equilibrium concentration of the product is _ 12 10 08 Concentration molL 06 04 02 00 0 2 4 6 00 10 Time min Select an answer and submit. A chemical reaction that has the general formula of na an is best classified as a reaction. For styrene deltaGnought of fluid 298 21318 kJmol.

Forward reaction rate is faster than the reverse and concentration is equal. The rates of the forward and reverse reactions are equal. Mar 15 2022.

The value of Q c must increase in order for the reaction to reach equilibrium. A chemical reaction that has the general formula of ab a b is best classified as a reaction. We can represent atoms by listing the number of protons neutrons and electrons-for example 2p 2n0 2e- for helium.

See both forward and reverse reactions have halted or d The rates of the forward and reverse reactions are equal. The rates of the forward and reverse reactions are equal. Answered expert verified.

C6H5CH CH2g H2g C6H5C2H5g The system initially contains 3 mol H2 for each mole of styrene. At equilibrium the concentrations of reactants and products do not change. When does the given chemical system reach dynamic equilibrium.

The reaction shown below reaches equilibrium with the concentrations H2O2 equals 015 H2O equals 021 O2 equals 025 What is the equilibrium constant for this reaction. Which statement describes a chemical reaction at equilibrium. Forward reaction rate is faster than the reverse and concentrations are equal.

Which of the following statement describes a reversible chemical reaction that has reached equilibrium. So remember that when a reaction is in chemical equilibrium that means that the concentrations of the reactant and products remained stable. 3 The concentrations of the products and reactants are equal.

Chemical equilibrium is a term used to describe a balanced condition within a system of chemical reactions. DeltaHnought of fluid 298 14736 kJmol. A What is Ka K sub a at 600 degrees Celsius.

Many reactions are irreversible. 2 NO g Cl 2 g 2 NOCl g K 2000. 2 More liquid water molecules will change to water vapor until a new equilibrium is reached.

4 The additional bromine ions. 1 The rate of the forward reaction equals the rate of the reverse reaction. The forward and reverse reactions are proceeding at the same rate.

Which of the following statements describe a reaction that is at equilibrium. Whether the reaction is fast or slow 3. 049 Describes chemical.

Forward and reverse reaction rates are equal and concentration is conctant. See both forward and reverse reactions have halted or d The rates of the forward and reverse reactions are equal. 2 The reactants are completely consumed in the reaction.

Forward and revers reaction rates are equal and concentration is equal. The concentrations of products and reactions are equal Be the reaction is now irreversible. The system contains too much reactant and not enough product to be at equilibrium.

Which of the following statements correctly describes any chemical reaction that has reached equilibrium. Reactants will convert to products The Gibbs free energy has reached a minimum The forward reaction rate is not equal to the reverse reaction rate O The concentration of product is equal to the concentration of reactant.
