WebApr 1, 2024 · In most general chemistry textbooks, the pK a of water at 25 ºC is listed as 14.0. In many organic chemistry textbooks and some biochemistry texts, however, the pKa of water at 25ºC is listed as 15.7. This module describes the derivation of these two values and describes why the value of 15.7 should not be used.

However, in the specific case … WebJan 30, 2024 · ΔH = ΔU + ΔPV. If temperature and pressure remain constant through the process and the work is limited to pressure-volume work, then the enthalpy change is given by the equation: ΔH = ΔU + PΔV. Also at constant pressure the heat flow ( q) for the process is equal to the change in enthalpy defined by the equation: ΔH = q.
