Question

If a reaction is exothermic and has a negative ΔH, what will be the effect of increasing temperature?
Options
A Shifts equilibrium toward products
B No change in equilibrium
C Shifts equilibrium toward reactants
Correct Answer
D Increases rate constant
Correct Answer

Option C is the correct answer.

Detailed Explanation

For an exothermic reaction, heat is a product. Increasing temperature adds heat, which disturbs the equilibrium. According to Le Chatelier's principle, the system will shift to consume the added heat, favoring the endothermic (reverse) reaction, thus shifting the equilibrium toward reactants.

Hint

Treat heat as a product in an exothermic reaction. Which way will the equilibrium shift if you add a product?
