Solution: A reaction under certain conditions has an enthalpy change of ΔH= -118kJ. This means that 118kJ 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 container.5. if the reaction were carried out at constant volume.

Problem

A reaction under certain conditions has an enthalpy change of ΔH= -118kJ. This means that 118kJ 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 container.

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