(a) Interpretation: The standard heat of formation for N a C l and N a O H and the standard heat of reaction for electrolysis of brine should be determined. Concept introduction: Standard heat of reaction is the change in enthalpy when the reactant is converting into product for one mole compound and is determined at a standard condition of temperature that is 25 o C denoted by using symbol Δ H ^ r ∘ and its calculation is based on the enthalpy of formation of reactant and product. Standard heat of formation is the change in enthalpy when one mole of substance reacts to form product at 25 ∘ C and is denoted by Δ H f .
