QJEEM21Che759: JEE Main 2021 Chemistry - Class 11 JEEM21Che759 Solution: Consider the reaction The temperature at which K C = 20.4 and K …

Consider the reaction

N2O4(g)⇌2NO2(g)N_{2}O_{4}\left( g\right) \rightleftharpoons 2NO_{2}\left( g\right)

The temperature at which KC = 20.4 and KP = 600.1, is ____________ K. (Round off to the Nearest Integer). [Assume all gases are ideal and R = 0.0831 L bar K −- 1 mol −- 1]

Step-by-Step Verified Solution

N2O4(g) ⇌\rightleftharpoons 2NO2(g)

Δ\Delta ng = 2 −- 1 = 1

KP = KC(RT) Δ\Delta ng

600.1 = 20.4 (0.0831 ×\times T)1

⇒\Rightarrow T = 600.120.4×0.0831{{600.1} \over {20.4 \times 0.0831}} = 354 K
