Answer:

Explanation:
You calculate the energy required to break all the bonds in the reactants.
Then you subtract the energy needed to break all the bonds in the products.
2H₂ + O₂ ⟶ 2H-O-H
Bonds: 2H-H 1O=O 4H-O
D/kJ·mol⁻¹: 436 498 464

Answer:
a. increase
Explanation:
Based on the kinetic molecular theory of gases, the average kinetic energy of the system will increase.
- The average kinetic energy is heat
- If temperature increases, heat of a system will also rise.
- According the kinetic molecular theory "the temperature of the gas is a measure of the average kinetic energy of the molecules"
Therefore, due to the increase in temperature, the average kinetic energy of the system increases.
