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, 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
