For the following gases equilibrium, N _ 2 O _ 4 (g) ⇌ 2N O _ 2 (g)...

For the following gases equilibrium, N2O4(g)⇌2NO2(g){N}_{2}{O}_{4} \left(g\right) ⇌ 2N{O}_{2} \left(g\right)

KP{K}_{P} is found to be equal to KC.Thisisattainedwhentemperatureis{K}_{C}. This is attained when temperature is

Options

  1. A0oC{0}^{o} \text{C}
  2. B273 K
  3. C1 K
  4. D12.19 K

Correct answer

D. 12.19 K

Step-by-step solution

KP=KC(RT)Δng=KC(RT)2−1=KCRT{K}_{P} = {K}_{C}{\left(RT\right)}^{\Delta{n}_{g}} = {K}_{C}{\left(RT\right)}^{2 - 1} = {K}_{C}RT

T=KPKC×1R=10.0821=12.18K\text{T} = \dfrac{{K}_{P}}{{K}_{C}} \times \dfrac{1}{R} = \dfrac{1}{0.0821} = 12.18\text{K}
