NEET Chemistry Chemical Equilibrium MCQ Question
Type: MCQ-diagram based-Easy-Class 11
Consider a diagram representing the equilibrium reaction: PCl5(g) ⇌ PCl3(g) + Cl2(g). If the system is at equilibrium and the temperature is increased, what will be the effect on the equilibrium constant Kc?
A
Kc will increase
B
Kc will decrease
C
Kc will remain unchanged
D
Kc will become zero
Correct Answer
Option A
Detailed Explanation
The reaction is endothermic (ΔrH = 124.0 kJ/mol). Increasing the temperature favors the forward reaction, increasing Kc.
