Almost all catalysts work by lowering the activation energy of the reaction with no change in the free energy of the reaction
- So in this case we can say that palladium reduce automobile pollution by catalyzing the reaction between un-burned hydrocarbons and oxygen :
D. by decreasing the activation energy
Answer:

Explanation:
Hello,
In this case, the molar enthalpy of reaction is obtained by dividing the involved energy by the reacting moles:

Thus, it is important to notice that the compound "uses" the energy, it means that it absorbs the energy, for that reason the sign is positive. Moreover, computing the result in kJ/mol we finally obtain:

Best regards.
