Which of the following gives the temperature dependence of a reaction?
Answer & explanation
Correct answer: option 2
The temperature dependence of the rate of a chemical reaction can be accurately explained by Arrhenius equation.
k = Ae-Ea/RT
where A is the Arrhenius factor or the frequency factor. It is also called pre-exponential factor. It is a constant specific to a particular reaction. R is gas constant and Ea is activation energy measured in joules/mole (J mol–1).
