Explanation / Answer

Activation energy is the minimum energy required to start a chemical reaction.

Heat of reaction of Reaction A

Hrxn = (Product of energy - Reactant of Energy ) KJ/mol = (25-125)KJ/mol = (-100 KJ/mol)

Activation Energy of Reaction A

Ea = minimum energy required to start a chemical reaction = (150-125)KJ/mol = 25 KJ/mol

Heat of reaction of Reaction B

Hrxn = (Product of energy - Reactant of Energy ) KJ/mol = (50-25)KJ/mol = (+25 KJ/mol)

Activation Energy of Reaction B

Ea = minimum energy required to start a chemical reaction = (100-25)KJ/mol = 75 KJ/mol
