Homework Answers
1)
Energy of product is less than the energy of reactant.
So, energy is being released in the reaction.
This is exothermic reaction
Answer: exothermic
2)
Activation energy = energy of activated complex - energy of reactant
= 19 KJ
Answer: 19 KJ
3)
Delta E = energy of product - energy of reactant
= -392 KJ
Answer: -392 KJ
