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)

Answer»

K is INDEPENDENT of T
K decreases as T decreases
k increases as T decreases
K varies with addition of NO

Solution :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.
