Answers to Rate expression questions1. In terms of units, rate / k = concentrationx(mol dm-3 s-1) /(dm6 mol-2 s-1) = mol3 dm-9 = (mol dm-3)3 = concentration3Hence the units of the rate constant show that the reaction is third order overall.2. (a) From experiments 3 and 1, doubling [CH3COCH3(aq)] causes the rate to double hence the order of the reaction with respect to propanone is one.(b) From experiments 1 and 2 doubling...
