Webk is the specific reaction rate (constant) and is given by the Arrhenius Equation: Svante August Arrhenius (1859–1927) (summary, internal link) Svante August Arrhenius (1859–1927) (detailed, external link) Where: Where: E = activation energy (cal/mol) R = gas constant (cal/mol*K) T = temperature (K) A = frequency factor (units of WebThe overall reaction order is the sum of the orders with respect to each reactant. If m = 1 and n = 1, the overall order of the reaction is second order ( m + n = 1 + 1 = 2). The rate law: rate = k[H2O2] rate = k [ H 2 O 2] describes a reaction that is first order in hydrogen peroxide and first order overall.
