WebThe activation energy can be graphically determined by manipulating the Arrhenius equation. The activation energy can also be calculated algebraically if k is known at two … WebAug 26, 2024 · How to do it depends on the order of reaction and the setup. For example for zero order: A → B [ A] t = [ A] 0 − k t If we got 10% left after 90 seconds and we started with a concentration of 1 M this means: 0.1 = 1 − 90 k which means: k = 0.01 M / s Or for a second order reaction following 2 A → B: 1 [ A] t − 1 [ A] 0 = k t
