Question 43 • Chemistry

The enthalpy of formation of water is negative 285 point 8 kJ over mol What can be inferred from this statement?

Answer
A
Heat is absorbed during the process.
B
The enthalpy of the products is more than the enthalpy of the reactants.
C
The enthalpy of the products is equal to the enthalpy of the reactants.
D
Heat is released during the process.

Explanation

The enthalpy change for forming water is −285.8 kJ/mol. A negative enthalpy change means the products have lower enthalpy than the reactants, and the difference is released as heat. Therefore, heat is released during the process.
