Hess's law states that:
| 1. | The heat evolved in a given process is equal to the heat absorbed in the reverse process. |
| 2. | The heat evolved or absorbed in a chemical process is the same regardless of the pathway taken. |
| 3. | The heat of reaction depends on the temperature of the reaction. |
| 4. | The heat of reaction is directly proportional to the concentration of the reactants. |
