An exothermic reaction has 
. The uncatalysed forward activation energy is 
. A positive catalyst provides an alternative pathway in which the forward activation energy becomes 80 kJ 
. Which statements are correct?
(I) The rate of the forward reaction increases because the activation energy is reduced.
(II) The equilibrium constant at the same temperature changes due to the catalyst.
(III) The reverse activation energy is also reduced by 
relative to the uncatalysed reverse reaction.
Choose the most appropriate answer from the options given below:
