WebHess Law Questions Hess law or Hess law of constant heat summation is a relationship in physical chemistry given by German Hess, a Swiss-born Russian chemist. It states … WebExample: Carbon reacts with oxygen to form carbon dioxide releasing 94.3kcals of heat in a single step. Carbon can also react in a two-step process of forming an intermediate carbon mono-oxide, which again is converted to carbon dioxide. ( ΔH = – Heat released) C + O 2 → CO + 26.0 kcals. CO + O 2 → CO 2 + 68.3kcals. WebChoose your end point as the corner which only has arrows arriving. Now do the calculation: Hess's Law says that the enthalpy changes on the two routes are the same. That means that: ΔH - 3267 = 6 (-394) + 3 (-286) Rearranging and solving: ΔH = 3267 + 6 (-394) + 3 (-286) ΔH = +45 kJ mol -1 open shelves near stove
