According to Arrhenius equation rate constant k is equal to A e^(-Ea//RT) . Which of the following options represents the graph of In k vs 1/T ?

Arrhenius studies the effect of temperature on the rate of a reaction and postulted that rate constant varies with temperature exponentially as k=Ae^(E_(a)//RT) . Thuis method is generally used for finding the activation energy of a reaction. Keeping temperature constant, the effect of catalyst on the activation energy has also been studied. The pre-exponetial factor in the Arrhenius equation of a first order reaction has the unit : a) mol L^(-1)s^(-1) b) L mol^(1)s^(-1) c) s^(-1) d) dimensionless
