Which of the following is not correct?
- A Dissolution of \(\mathrm{NH}_4 \mathrm{Cl}\) in excess of water is an endothermic process
- B Neutralisation process is always exothermic
- C The absolute value of enthalpy \((\mathrm{H})\) can be determined experimentally
- D The heat of reaction at constant volume is denoted by \(\Delta E\)
Answer & Solution
Correct Answer
(C) The absolute value of enthalpy \((\mathrm{H})\) can be determined experimentally
Step-by-step Solution
Detailed explanation
The absolute value of enthalpy cannot be determined, only the change in enthalpy \((\Delta H)\) during a process can be determined.
