The rate of any chemical reaction increases with increasing temperature. This relationship is generally expressed in the form of the Arhenius Equation, k′ is the rate constant, T is the temperature (K), R is the gas constant (8.314 J/Kmol), Ea is the activation energy (J/mol), and A is called frequency factor. ln k′ = ln A - Ea/R(1/T) Since the rate of reaction is the change in concentration with respect to time, collect the concentrations at each interval and define k by: k = (C1 - C0)/30 (where C1 is the current measured concentration and C0 is the previous concentration).
