Rate Laws and Reaction Order Pathways to Chemistry

WebMay 8, 2015 · Consider the following reversible reaction in which the reaction is first order in both directions: [ A] ↽ − − ⇀ [ B] k a is the rate constant for the forward reaction and k b is the rate constant for the reverse reaction. 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.
