Question

A. The concentration of the reactant A is equal to the concentration of the product B. B. No new molecules of product B are formed. C. The concentration of reactant A is constant over time. D. The rate of the reverse reaction is equal to the rate of the forward reaction and both rates are equal to zero. E. None of the above (A-D) is true.


2.) If the concentration of the product were to double in the reaction A B, what would happen to the equilibrium constant Kand the reaction quotient Q?
A. The value of K would double and the value of Q would remain unchanged. B. The value of K would remain unchanged and the value of Q would double. C. The values of both K and Q would double. D. The values of both K and Q would remain unchanged. E. The answer would depend on the initial concentration of the product.

Explanation / Answer

1. C

At equilibrium concentration of reactants and products become constant.

2. B

K only depend on temperature.
