WebJul 19, 2024 · In order to find K in a first order rate law, you need to know the initial concentration of the reactant, the final concentration of the reactant, and the reaction time. You then use the following equation to calculate K: K = (ln (final concentration) – ln (initial concentration)) / reaction time. For example, if you had a reaction that went ... Web3) The rate law is this: rate = k [A] [B] 2. 4) Note that the comparison in (2) can be reversed. Consider that the concentration of B is doubled as you go from exp. 3 to exp. 1. When the concentration is doubled, the rate goes up by a factor of 4 (which is 2 2). 5) We can use any set of values to determine the rate constant: rate = k [A] [B] 2
