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 <u>higher</u> 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 <u>left</u> side of the equation.
