For the gaseous phase reaction, N2 + O2 ⇌ 2NO, ΔH = + 80 kJ/kg. mole; the decomposition of NO is favoured by____________________?
Correct answer: B
Explanation
The reaction is endothermic (ΔH = +80 kJ/mol). Lowering the temperature shifts the equilibrium to the left (reverse reaction), favoring the decomposition of NO.
