Question
Which statements are true regarding chemical equilibrium?
A. The rate of the forward reaction is equal to the rate of the reverse reaction.
B. The rate constant for the forward reaction is equal to the rate constant for the reverse reaction.
C. The equilibrium constants for the forward and reverse reactions both are 1.
D. The concentration of reactants is equal to the concentration of products.
E. The concentrations of the reactants and the products are constant.
You may select zero, one, or many answers.
Explanation / Answer
Ans: Choices A and E are correct.
Ths reaction is said to be in equillibrium , if the concentration of reactants and products do not change with respect to time. This means that the forward and the backward reaction rates are equal. The concentrations are constant , but it does not mean that they both are equal to each other. The rate constants of the forward and reverse reactions are inverse of each other.
