The absolute value of enthalpy cannot be determined, only the change in enthalpy (Δ H) during a process can be determined.

Q. Which of the following is not correct?

Dissolution of $N H_{4} Cl$ in excess of water is an endothermic process

Neutralisation process is always exothermic

The absolute value of enthalpy (H) can be determined experimentally

The heat of reaction at constant volume is denoted by $Δ E$

The absolute value of enthalpy cannot be determined, only the change in enthalpy $(Δ H)$ during a process can be determined.
