Question

The decomposition reaction of CO2(g) to produce carbon and oxygen gas consumes 462 kJ of energy. The energy levels of the products are ________ than the energy level of the reactant, and the heat appears on the _______ side of the equation.

Answer 1

Answer:

higher, left

Explanation:

Given that the reaction consumes 462 kJ of energy. It means that the reaction is a endothermic reaction.

In the energy profile of the endothermic diagrams, The reactants are at a very low level as compared to the products and hence, energy is supplied to overcome this difference.

Hence, The energy levels of products are higher than the energy level of reactant.

Hence, already stated, heat is required by the reaction and thus heat is written to the reactant side which is to the left side of the equation.
