Answer:

The enthalpy of the reaction is –184.6 kJ, and the reaction is exothermic.

Explanation:

The branch of science which deals with chemicals is called chemistry.

The options given in the question are wrong. So according to the data, the correct answer is exothermic.

In the reaction, the energy given in the question is -92.3. The negative sign represents the heat loss from the reaction.

The release out of the energy from the reaction is called an exothermic reaction.

Hence, the correct answer is exothermic.
