Question
State and explain Arrehenius equation. How can we determine the activation energy of a reaction using this equation?
Solution
where k is rate constant, A is Arrhenius of frequency factor, Ea is energy of activation, T is absolute temperature. This equation is called Arrhenius equation.
Taking log, we get
Plot of log k versus 1 / T is a straight line with a negative slope. The slope of the line is equal to
