"WebThe overall order of a reaction can be determined by adding the exponents. For example, if the rate law is Rate = k[A] 2 [B], the order with respect to [A] is 2, the order with respect to [B] is 1, and the overall order for the reaction is equal to 3. The reaction is 2 nd order in [A] and 1 st order in [B]. The reaction is third order overall. " - Order in kinetics

WebThe overall reaction order is simply the sum of orders for each reactant. For the example rate law here, the reaction is third order overall (1 + 2 = 3). A few specific examples are shown below to further illustrate this concept. The rate law: rate = k[H2O2] describes a reaction that is first order in hydrogen peroxide and first order overall. WebThe activation energy of an isomerization reaction which obeys 1st-order kinetics is known to be 100 kJ/mol and the pre-exponential of reaction is 1.666 x 103 cm/s.
