Question

A reaction under certain conditions has an enthalpy change of ∆H = −118 kJ. This means that 118 kJ of heat would be liberated

1. if the reaction were carried out at constant pressure.

2. if the reaction were carried out at constant concentrations.

3. no matter how the reaction were carried out.

4. if the reaction were carried out in any type of calorimeter.

5. if the reaction were carried out at constant volume.
