Answer:
26kJmole,84kJmole
Explanation:
A catalyst lowers the activation energy between reactants and products. Once this energy barrier is lowered, reactants are converted into products faster.
However, the enthalpy change of a reaction is constant both in the catalysed and uncatalysed reaction.
The activation energy of the uncatalysed reaction must be higher than the activation energy of the catalysed reaction. Hence the answer above.
