Question

Which term below best matches a potential energy diagram in which the potential energy value of the reactants is less than that of the products? A.) Activation energy. B.) Reaction Pathway C.) Exothermic Process D.) Endothermic Process

Answer 1

Answer: D.) Endothermic Process

Explanation: Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and $\Delta H$ for the reaction comes out to be positive.

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and $\Delta H$ for the reaction comes out to be negative.

Activation energy is defined as the extra energy required by the reactants to cross the energy barrier to convert into products.

Answer 2

The correct answer is D, the Endothermic Process.
