The difference between the heat content of the products and the heat content of the reactants is heat of a reaction
Step-by-step explanation:
- The Heat of Reaction (also known and Enthalpy of Reaction) is the change in the enthalpy of a chemical reaction that occurs at a constant pressure.
- Enthalpy is important because it tells us how much heat (energy) is in a system.
- Three factors can affect the enthalpy of reaction: The concentrations of the reactants and the products. The temperature of the system. The partial pressures of the gases involved
- Heat is important because we can extract useful work from it. In terms of a chemical reaction, an enthalpy change tells us how much enthalpy was lost or gained, enthalpy meaning the heat energy of the system.
- It is a thermodynamic unit of measurement useful for calculating the amount of energy per mole either released or produced in a reaction.
- A negative enthalpy represents an exothermic reaction, releasing heat. A reaction that absorbs heat is endothermic. Its enthalpy will be positive, and it will cool down its surroundings. This reaction is exothermic.
