NEET Physics Entropy MCQ Question

Type: MCQ-numerical-Medium-Class 11

At 60°C, dinitrogen tetroxide is 50% dissociated. What is the equilibrium constant Kp for this reaction?

A

33 atm

B

47 atm

C

0.1239 atm

D

4 × 10^2 atm

Correct Answer

Option A

Detailed Explanation

When N2O4 is 50% dissociated, the equilibrium constant Kp is calculated from the partial pressures: Kp = (pNO2)^2 / pN2O4 = 1.33 atm.
