WebDelta h in chemistry, also written as ∆H, refers to the change of enthalpy in a thermodynamic system caused by either absorption or emission of thermal energy. In simpler words, we may elaborate delta h as the total change in the system’s heat before and after a chemical reaction. Delta is symbolically represented by ∆and refers to “change”. WebBy combining the bond enthalpy values for all of the bonds broken and formed during a reaction, it's possible to estimate the total change in potential energy of the system, which is Δ H rxn \Delta\text H_{\text{rxn}} …
