The description for the enthalpy change of overall reaction for the above reaction coordinate diagram is given as-
The enthalpy change for the above reaction is the energy released as heat during the progress of the reaction. The change in enthalpy for the above reaction is -ve as the products have lower energy than the reactants and hence, the reaction is an exothermic or heat-releasing reaction. The enthalpy change for the overall reaction is denoted by the portion X in the above reaction coordinate diagram.

The standard enthalpy of a reaction, AH, is the energy or enthalpy change associated with transforming reactants into products, where "standard", denoted °, implies reaction conditions of 25°C, 1 atm and/or 1 M. Standard enthalpies of a reaction can be estimated by assuming that all reactant bonds are broken before forming all product bonds: AHTD =( enthalpies of bonds broken) - (2 enthalpies of bonds formed) Using the information below, calculate AH°r (kJ) for the reaction of H2(g) + Cl2(g)...
