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.
