Question

For the gas phase reaction 2NO(g) $\rightleftharpoons$N2(g) + O2(g); ΔH = – 43.5 kcal. Which one of the following is true for the reaction N2(g) + O2 (g) $\rightleftharpoons$2NO(g)?

Options

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.

Solution

N2(g) + O2(g) $\rightleftharpoons$2NO(g); OH = +43.5 Kcal

For endothermic reactions, Keq increases with the increase in temperature.
