The rate of a reaction depends upon the ...

The rate of a reaction depends upon the temperature and is quantitatively expressed as
`k=Ae^((-Ea)/(RT)`
i) If a graph is plotted between log k and 1/T, write the expression for the slope of the reaction?
ii) If at under different conditions `E_(a1)` and `E_(a2)` are the activation energy of two reactions. If `E_(a1) = 40 J// "mol and "E_(a2) = 80 J// "mol"`. Which of the two has a larger value of the rate constant?
