Question

As temperature is increased, the equilibrium of a gaseous reaction will always

• A. shift to the right
• B. shift to the left
• C. remains constant
• D. the answer cannot be determined from the given information

Hint:

Always consider the enthalpy change (ΔH) when predicting the effect of temperature changes on equilibrium.

Answer 1

The Correct Option is D

The effect of temperature on equilibrium depends on whether the reaction is exothermic or endothermic.
According to Le Chatelier’s Principle, if the reaction is exothermic, increasing the temperature will shift the equilibrium to the left.
If it is endothermic, increasing the temperature will shift the equilibrium to the right.
Therefore, the direction cannot be determined without additional information.
