explain and use the terms catalyst and catalysis: (a) explain that, in the presence of a catalyst, a reaction has a different mechanism, i.e. one of lower activation energy (b) explain this catalytic effect in terms of the Boltzmann distribution (c) construct and interpret a reaction pathway diagram, for a reaction in the presence and absence of an effective catalyst

describe the role of NO and NO\(_2\) in the formation of acid rain both directly and in their catalytic role in the oxidation of atmospheric sulfur dioxide

construct and interpret a reaction pathway diagram, in terms of the enthalpy change of the reaction and of the activation energy
