Answer: The correct answer is Option B.
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.
[tex]\Delta H_{rxn}=\Delta H_{products}-\Delta H_{reactants}=+ve[/tex]
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.
[tex]\Delta H_{rxn}=\Delta H_{products}-\Delta H_{reactants}=-ve[/tex]
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.
