Consider the reaction N2O4(g)⇌2NO2(g){N}_{2}{O}_{4} ( g ) ⇌ 2{NO}_{2} ( g ) The temperature at which KC=20.4andKP=600.1,{K}_{C} = 20 . 4 and {K}_{P} = 600 . 1, is ______ KK. (Round off to the Nearest Integer). [Assume all gases are ideal and R=0.0831LR = 0 . 0831L bar K−1mol−1]{K}^{- 1}{mol}^{- 1}]

Correct answer

0

Step-by-step solution

N2O4(g)⇌2NO2(g);Δng=2−1=1{N}_{2}{O}_{4} ( g ) ⇌ 2{NO}_{2} ( g ) ; {\Delta n}_{g} = 2 - 1 = 1

Now, Kp=Kc⋅(RT)∆ng{K}_{p} = {K}_{c} \cdot {( RT )}^{∆ {n}_{g}}

or, 600.1=20.4×(0.0831×T)1600 . 1 = 20 . 4 \times ( 0 . 0831 \times T{)}^{1}

∴T=353.99K=354K∴ T = 353 . 99K = 354K
