The enthalpy of formation of water is –285.8 kJ/mol. What can be inferred from this statement? The enthalpy of the products is equal to the enthalpy of the reactants. Heat is absorbed during the process. Heat is released during the process. The enthalpy of the products is more than the enthalpy of the reactants.

Heat is released during the process.

Explanation:

From the information provided in question, the enthalpy of formation of water is –285.8 kJ/mol. This is simply an exothermic reaction.

The negative sign indicates that the enthalphy of the reactants is more than the enthalphy of the products and as such, heat is released from the system into the surroundings.
