Explanation:
Physical because it’s compound doesn’t change
Answer:
E = 17 kJ
Explanation:
The enthalpy of the reaction is:
<u>Where</u>:
Ep: is the energy of the products
Er: is the energy of the reactants
Similarly, the enthalpy of the reaction is related to the activation energy forward (
) and to the activation energy reverse (
) as follows:
Having that ΔH = 44 kJ and = 61 kJ, the activation energy of the reverse reaction is:
Therefore, the activation energy of the reverse reaction is 17 kJ.
