Answer:
The correct answer is :'It is endothermic because the energy required to break bonds in the reactants is greater than the energy released when the products are formed'.
Explanation:
Endothermic reactions are defined as the reactions in which energy of products is more than the energy of the reactants. In these reactions, energy is absorbed by the system.
The energy required to break the bonds in the reactant is more that the energy released when the products are formed.
The total enthalpy of the reaction comes out to be positive.
Exothermic reactions are defined as the reactions in which energy of reactants is more than the energy of the products. In these reactions, energy is released by the system.
The energy required to break the bonds in the reactant is less that the energy released when the products are formed.
The total enthalpy of the reaction comes out to be negative.
ΔH for reactants = -750 kJ/mol
ΔH for products = 920 kJ/mol
ΔH for reactants < ΔH for products
It is endothermic because the energy required to break bonds in the reactants is greater than the energy released when the products are formed
Answer: Option (b) is the correct answer.
Explanation:
Since energy of reactants is less than the energy of products. Therefore, it means energy is absorbed during the reaction.
As the energy required to break the bonds in the reactants is greater than the energy released when products are formed.
Therefore, it is an endothermic reaction.
Thus, we can conclude that the statement, it is endothermic because the energy required to break bonds in the reactants is greater than the energy released when the products are formed is correct.
