WebThe unit for the rate constant differs depending on the order of the reaction. This is because the units have the be equivalent on either side of a rate equation. So for a first order reaction the rate law is: Rate = k [A], where k is the rate constant and A is the reactant to the first power. WebIf n = 1, the reaction is first-order, and the rate is directly proportional to the concentration of A. If n = 2, ... 3.60: 9.6 x 10-2: Using the data, determine the order of the reaction and calculate the rate constant: answer.
