Question: What is the effect of increasing the temperature on the equilibrium constant Kc for an endothermic reaction? (2023)

Options:

Correct Answer: Kc increases

Exam Year: 2023

Solution:

For an endothermic reaction, increasing the temperature shifts the equilibrium to the right, thus increasing the value of Kc.

What is the effect of increasing the temperature on the equilibrium constant Kc for an endothermic reaction? (2023)

Step 1: Understand what an endothermic reaction is. It is a reaction that absorbs heat from its surroundings.
Step 2: Know that the equilibrium constant Kc is a value that tells us the ratio of products to reactants at equilibrium.
Step 3: Recognize that increasing the temperature adds heat to the system.
Step 4: For an endothermic reaction, adding heat (increasing temperature) favors the formation of products.
Step 5: When the equilibrium shifts to the right (towards products), the concentration of products increases.
Step 6: As the concentration of products increases, the value of Kc also increases.
