AP Chemistry 7.2 A Explain the Relationship Between the Direction in Which a Reversible Reaction Proceeds and the Relative Rates of Questions question 1

[Maximum number: 1]

Hydrogen gas reacts with iodine gas at constant temperature in a sealed rigid container. The gases are allowed to reach equilibrium according to the equation above. Which of the following best describes what will happen to the reaction immediately after additional iodine gas is added to the system?

A

The rates of both the forward and reverse reactions decrease.

B

The rates of both the forward and reverse reactions do not change.

C

The rate of the forward reaction becomes greater than the rate of the reverse reaction.

D

The rate of the forward reaction becomes less than the rate of the reverse reaction.
