WebFirst Order rate = k[A]1 = k[A] The rate is directly proportional to the concentration. If you double the concentration, you double the rate. If you triple the concentration, you triple the rate. If you halve the concentration, you halve the rate, and so on. Second Order rate = k[A]2 The rate is proportional to the square of the concentration. 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. smart earphones

"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.
