(ii) Dinitrogen pentoxide, N2Os, may be formed in the atmosphere by the mechanism given below, in which * denotes a molecule in an excited state and M is a quencher molecule in the gas-phase: NO, +NO; ky »N,0,- * N,O k_ ► NO+ NO, k k N,O,*+M ►N.0, +M Using the Steady State Approximation, derive an expression for the observed rate coefficient (koba) for the overall reaction between NO2 and NO3 to make N2Os. What does the expression for koos become at very high pressures of M? [10 marks]
