Which statement is correct? the enthalpy of the reaction is –184.6 kj, and the reaction is exothermic. the enthalpy of the reaction is –184.6 kj, and the reaction is endothermic. the enthalpy of the reaction is 184.6 kj, and the reaction is endothermic. the enthalpy of the reaction is 184.6 kj, and the reaction is exothermic.

The correct statements are :

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

2. The enthalpy of the reaction is 184.6 kJ and the reaction is endothermic.

Step-by-step explanation:

Enthalpy of reaction is amount of heat absorbed or released during the reaction.

If energy is required, enthalpy of reaction is positive and if energy is released the enthalpy of reaction is negative.

Exothermic reaction: The chemical change is accompanied by the release of heat energy

Endothermic reaction: The chemical change is accompanied by the absorption of heat energy.

So, from the above definitions, it is clear that the enthalpy of reaction of a exothermic reaction is negative and that of a endothermic reaction is positive.
