Given the subsequent relationship k = Ce-(changeG*/RT) OR k? e-(changeG*/RT) where C is a unit of proportionality constant . Obtain the relationship that illustrates how the energy of activation can be expressed as the change of enthalpy from reactants to the activated complex which is the top of the energy barrier as well as the pre-exponential term is entropy related
Calculate the vapor pressure of water above a solution prepared by dissolving 26.9 g of glycerin (C3H8O3) in 183 g of water at 343 K. Vapor Pressure (torr) at 343 (or 70) is 233.7 torr
