For the reaction 2NO(g)⇌N2(g)+O2(g),ΔH=−180 kJ mol−1. Which of the following facts does not hold well?
The dissociation of NO is favored more at high temperature
Pressure changes do not affect equilibrium constant and hence equilibrium concentrations are not changed. Since the reaction is exothermic, increasing temperature shifts the equilibrium towards the reactant side. Hence, lesser of NO is dissociated.
