This equation represents the reversible reaction in which nitrogen and hydrogen combine to produce ammonia. $\text{N}_2 + 3\text{H}_2 \rightleftharpoons 2\text{NH}_3$. The forward reaction gives out heat. Which statement is correct when the temperature is increased?
- AThe activation energy increases.
- BThe equilibrium shifts to form more ammonia.
- CThe rate of the forward reaction decreases.
- DThe rate at which ammonia decomposes increases.
