Consider the following equilibrium reaction having gaseous reactants and products.
4HCl + O2 ⇌ 2H2O + Cl2

Which of the following would result from increasing the concentration of H2O?(4 points)

A. The rate of the backward reaction increases.
B. The concentration of hydrochloric acid decreases.
C. The rate of forward reaction increases.
D. The concentration of chlorine increases.

Answer :

Answer:

A. The rate of the backward reaction increases.

Explanation:

The stress caused by increasing the H2O concentration would shift the system to the left, producing more reactants to counter the stress of added H2O. This means the rate of the backward reaction would increase.

Answer:

A
