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.
