16.1/R2.2.9 Deduce the Rate Expression for a Reaction from Experimental Data [HL IB Chemistry]

Описание к видео 16.1/R2.2.9 Deduce the Rate Expression for a Reaction from Experimental Data [HL IB Chemistry]

Examination of rate data will show relationships between the [reactants] and the rate of reaction. If the rate does not change when the [reactant] does -- the order of reaction will be zero for this reactant. A directly proportional relationship gives an order of one, and a squared relationship gives a two. Units for k will vary with the order of reaction; 1st order gives s-1, 2nd order mol-1 dm-3 s-1, 3rd order mol-2 dm6 s-1.
