Question: In a reaction at equilibrium, what effect does increasing the temperature have on an exothermic reaction?

Options:

Correct Answer: Shifts equilibrium to the left

Solution:

For an exothermic reaction, increasing the temperature shifts the equilibrium to the left, favoring the reactants, as the system absorbs heat.

In a reaction at equilibrium, what effect does increasing the temperature have on an exothermic reaction?

Step 1: Understand that an exothermic reaction releases heat.
Step 2: Recognize that at equilibrium, the reaction can go in both directions: forward (products) and backward (reactants).
Step 3: Know that increasing the temperature adds heat to the system.
Step 4: Apply Le Chatelier's Principle, which states that if a system at equilibrium is disturbed, it will shift to counteract the disturbance.
Step 5: Since the reaction releases heat, adding heat (increasing temperature) will cause the equilibrium to shift to the left, favoring the reactants.

Le Chatelier's Principle – This principle states that if a system at equilibrium is subjected to a change in temperature, pressure, or concentration, the system will adjust to counteract that change.
Exothermic Reactions – Exothermic reactions release heat, and increasing temperature can shift the equilibrium position.
