The following is an Arrhenius plot of a first-order reaction. The rate constant is measured in units of s–1. Based on this Arrhenius plot, what is the activation energy (Ea) of the reaction? Hint: Use the Arrhenius linear form shown below to determine the activation energy (Ea). Match the graph to the equation: R is the gas constant (8.314 J/mol . K)
