For the gas phase reaction `2NO(g)hArrN_(2)(g) + O_(2)(g) , DeltaH = -43.5` kcal,which one of the following is true for `N_(2)(g) + O_(2)(g)2NO(g)`

A

K is independent of T

B

K decreases as T decreases

C

k increases as T decreases

D

K varies with addition of NO

Text Solution

Verified by Experts

The correct Answer is:
B
The given reaction `N_(2)(g) + O_(2)(g)hArr2NO(g)` is endothermic.Therefore, according to Le-Chaltlier’s Principle , high temperature favours forward reaction and hence K increase as T increase or K decrease as T decreases.
