**Question:** Which of the following statements about enthalpy is false?**Options:** - The SI unit of enthalpy is J.- At constant pressure, the enthalpy change is equal to the heat absorbed or released.- Enthalpy is an extensive property.- Enthalpy is a state function.- The change in enthalpy of a process cannot be negative.**Correct Answer:** - The change in enthalpy of a process cannot be negative. **Explanation:** In an educational context, it's important to understand that the change in enthalpy (ΔH) can indeed be negative. This occurs in exothermic reactions where heat is released, resulting in a decrease in enthalpy. The other options correctly describe properties of enthalpy, including its unit (joules), its nature as an extensive property and a state function, and its relationship with heat at constant pressure.

Enthalpy: * The energy contained in chemical bonds that can be converted into heat is known as…
