Question

The reaction diagram illustrates what type of reaction?
A.)Exothermic
B.)Endothermic

Answer 1

Answer: The correct answer is Option A.

Step-by-step explanation:

There are 2 types of reactions based on heat transfer:

Endothermic reactions: They 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 total enthalpy of the reaction
`(\Delta H)` comes out to be positive.

`\Delta H=\Delta H_{\text{Products}}-\Delta H_{\text{reactants}}=+ve`

Exothermic reactions: They 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 total enthalpy of the reaction
`(\Delta H)` comes out to be negative.

`\Delta H=\Delta H_{\text{Products}}-\Delta H_{\text{reactants}}=-ve`

From the given reaction diagram:

Energy of products is less than the energy of reactants. So, the energy is released during the reaction.

Hence, the correct answer is Option A.

Answer 2

The answer will be B that is endothermic reaction.

The above image is an example of endothermic reaction as the energy of product is more than that of reactant that is energy is absorbed. In endothermic reactions energy is absorbed while in exothermic reaction, energy is released.

So here the answer will be B that is endothermic reaction as here energy of product is more than reactant .
