Answer

Answer:

C. It increases with a decrease in the concentration of $H_2(g)$. D. It decreases with an increase in the concentration of $S_2(g)$.

Explanation:

Step1: Le - Chatelier's principle

According to Le - Chatelier's principle, for a reversible reaction at equilibrium, if a change is made to the reaction conditions, the system will adjust to counteract that change.

Step2: Analyze $S_2(g)$ effect

The forward reaction is $2H_2S(g)\rightleftharpoons2H_2(g)+S_2(g)$. When the concentration of $S_2(g)$ (a product) increases, the system will shift in the reverse - direction to reduce the added $S_2(g)$. So the rate of the forward reaction decreases.

Step3: Analyze $H_2(g)$ effect

When the concentration of $H_2(g)$ (a product) decreases, the system will shift in the forward - direction to replenish the $H_2(g)$. So the rate of the forward reaction increases. When the concentration of $H_2(g)$ increases, the system shifts in the reverse - direction and the rate of the forward reaction decreases.
