Question

For exothermic reactions, which condition is applicable for equilibrium constant K?

(a) K decreases with increasing temperature

(b) K decreases with decreasing temperature

(c) Positive ΔH°rxn with increasing temperature; K increases

(d) Negative ΔH°rxn with increasing temperature; K increases

The question was posed to me by my college director while I was bunking the class.

I'd like to ask this question from Basic Reaction Theory topic in division Homogenous Reactions of Bioprocess Engineering

Answer 1

Correct option is (a) K decreases with increasing temperature

For explanation I would say: For exothermic reactions with negative ΔH°rxn, K decreases with increasing temperature. For endothermic reactions and positive ΔH°rxn , K increases with temperature.
