Easy· Temperature Dependence of the Rate of a Reaction (Arrhenius Equation)· +4 / −1
Given below is an expression for the rate constant of a first-order reaction occurring at a certain temperature, TT (K).
ln⁡k=14.34−1.25×104T\ln k=14.34-\frac{1.25\times10^{4}}{T}
The energy of activation in kcal mol−1^{-1} for the reaction is: (Given: kk in s−1^{-1}, R=1.987 cal mol−1K−1R=1.987\ \text{cal mol}^{-1}\text{K}^{-1})
