ΔH is positive for the equilibrium N2 (g) + O2 (g) ↔ 2 NO (g). If we lower the temperature,

(A) the equilibrium shifts to the left (more N2 + O2 gases formed)

(B) the equilibrium shifts to the right (more NO gas formed)

(C) Equilibrium does not shift because there are the same number of molecules on left side as on the right

(D) Equilibrium does not shift because temperature does not affect the reaction rates
