EEE Rates of Reaction 3.0 / 5 based on 1 rating ? ChemistryRatesA2/A-levelOCR Created by: FfionCreated on: 07-05-13 14:39 The rate of reaction is: the rate of change of concentration of a reactant or product with time 1 of 8 The rate equation is: the equation showing how the rate depends on the concentrations 2 of 8 Generally, as the temperature increases, k: Increases 3 of 8 For 0 order reactions, the units of k are: mol.dm-3 s-1 4 of 8 For 0 order reactions, how does the half life of A change as the reaction proceeds? Decreases 5 of 8 For 1st order reactions, how does the half life of A change as the reaction proceeds? Stays Constant 6 of 8 For 2nd order reactions, how does the half life of A change as the reaction proceeds? Increases 7 of 8 Which is the rate determining step in a reaction? The slowest step 8 of 8
