Explanation / Answer

1) Activation energy = (enthapy at transition state - enthalpy of reactants) = 400 kJ/mol - 250 kJ/mol = 150 kJ/mol

2) enthalpy change of the uncatalyzed reaction = (entahpy of product - entahpy of reactants) = 100kJ/mol - 250 kJ/mol = -150kJ/mol

3) Activation energy = (enthapy at transition state - enthalpy of reactants) = 400 kJ/mol - 100 kJ/mol = 300 kJ/mol

4) enthalpy change of the uncatalyzed reaction = (entahpy of product - entahpy of reactants) = 250kJ/mol - 100 kJ/mol = 150kJ/mol
