WebApr 8, 2024 · Henry’s law states that at a constant temperature, the amount of gas particles dissolved in the liquid solution is directly proportional to the gas partial pressure which is above the liquid. The mathematical formula of Henry’s law is shown below. P α C P = K H C Where, *P is the partial pressure of the gas WebMar 13, 2024 · Hess's law states that the energy change in an overall chemical reaction is equal to the sum of the energy changes in the individual reactions comprising it. In other words, the enthalpy change of a chemical reaction (the heat of reaction at constant pressure) does not depend on the pathway between the initial and final states.
