How do we do this problem? The solution manual is misleading regarding the substitution of Ea.

7E.4 The presence of a catalyst provides a reaction pathway in which the activation energy of a certain reaction is reduced from 125 kJ/mol to 75 kJ/mol.

a) by what factor does the rate of the reaction increase at 298K, all other factors being equal?

b) by what factor would the rate change if the reaction were carried out at 350K instead?
