NEET Chemistry Chemical Equilibrium MCQ Question
Type: MCQ-numerical-Medium-Class 11
Given the reaction: N2O4 (g) ⇌ 2NO2 (g) with an initial pressure of N2O4 at 4.98 bar and a total pressure at equilibrium of 9.15 bar, what is the equilibrium partial pressure of NO2?
A
8.34 bar
B
4.98 bar
C
4.17 bar
D
0.81 bar
Correct Answer
Option A
Detailed Explanation
Using the equilibrium condition p_total = p_N2O4 + p_NO2 and given values, x is found to be 4.17 bar. Therefore, p_NO2 = 2x = 2 × 4.17 = 8.34 bar.
