It also equals negative activation energy over temperature, times the natural log of the ratio of the equilibrium constant to the pre-exponential factor, by the Arrhenius equation.
This constant appears in the denominator of the variable that multiples the square of the quantity one minus the ratio of solubility parameters to give the enthalpic component of the Flory-Huggins interaction parameter. This constant equals the molar mass times the difference in specific heat for a compound at constant pressure and that compound at constant volume. It also equals negative activation energy over temperature, times the natural log of the ratio of the equilibrium constant to the pre-exponential factor, by the Arrhenius equation. Boltzmann's constant equals this constant divided by Avogadro's number. For 10 points, name this constant that also equals the product of pressure and volume divided by the product of moles and temperature by the law after which it is named.
