Question 3

The decomposition of nitrogen dioxide is represented by the equation: \(2\text{NO}_2(g) \rightleftharpoons 2\text{NO}(g) + \text{O}_2(g)\) The activation energy for the forward reaction is \(112\) kJ mol\(^{-1}\) and the activation energy for the reverse reaction is \(250\) kJ mol\(^{-1}\). Explain why this reaction is reversible by referring to the activation energies of the forward and reverse reactions.
