Question

Consider the following energy diagram.

Do the reactants or products have more enthalpy?
A. reactants
B. products

Answer 1

The products because the graph shows ethalpy increasing the higher it is, and since products are on the right side, and the right side is higher than the left, products must be the answer. Though I could be interpreting the graph wrong.

Answer 2

Answer: The correct answer is Option B.

Step-by-step explanation:

The given energy diagram is determining that the reaction is an endothermic reaction.

Endothermic reaction is defined as the chemical reaction where energy of the products is more than the energy of the reactants. This results in the absorption of heat and total enthalpy change of the reaction comes out to be positive.

`\Delta H_(rxn)=\Delta H_(products)-\Delta H_(reactants)=+ve`

Exothermic reaction is defined as the chemical reaction where energy of the products is less than the energy of the reactants. This results in the release of heat and total enthalpy change of the reaction comes out to be negative.

`\Delta H_(rxn)=\Delta H_(products)-\Delta H_(reactants)=-ve`

In the given diagram, product is lying above the reactant, so energy of it will be more than the reactants.

Hence, the correct answer is Option B.
