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

define activation energy, \( E_A \), as the minimum energy required for a collision to be effective

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
