The Hreaction is the difference between Hf, products and Hf, reactants
The standard enthalpy change of a reaction (delta H) is related to the standard enthalpy of formation (delta Hf) of the products and reactants involved in the reaction by the equation: delta H = Σ(Products delta Hf) - Σ(Reactants delta Hf). This equation relates the enthalpy change of a reaction to the enthalpies of formation of the substances involved in the reaction.
To calculate the heat of reaction in a chemical reaction, you can use the formula: H (Hf products) - (Hf reactants), where H is the heat of reaction, Hf is the standard heat of formation, and the symbol means to sum up the values for all products and reactants. This formula helps determine the amount of heat released or absorbed during a chemical reaction.

The reaction HCl + F2 --> HF + Cl2 is a redox reaction, specifically a single replacement reaction. Hydrogen chloride (HCl) reacts with fluorine (F2) to produce hydrogen fluoride (HF) and chlorine (Cl2).
