understand, in terms of collision theory, the effect of a change in concentration, temperature, pressure and surface area on the rate of a chemical reaction

understand that reactions only take place when collisions take place with sufficient energy, known as activation energy

be able to calculate the rate of a reaction from:

i) data showing the time taken for reaction
ii) the gradient of a suitable graph, by drawing a tangent, either for initial rate, or at a time, t

understand qualitatively, in terms of the Maxwell-Boltzmann distribution of molecular energies, how changes in temperature affect the rate of a reaction

understand the role of catalysts in providing alternative reaction routes of lower activation energy

be able to draw the reaction profiles for uncatalysed and catalysed reactions

be able to interpret the action of a catalyst in terms of a qualitative understanding of the Maxwell-Boltzmann distribution of molecular energies

understand the use of a solid (heterogeneous) catalyst for industrial reactions, in the gas phase, in terms of providing a surface for the reaction

understand the economic benefits of the use of catalysts in industrial reactions
