I hope this isn't deemed school related. It is something I learned in school, but I'm now trying to figure out a reaction model for my work. In the process of calculating the reaction constant, usually you first determine the Gibbs energy of formation of each species, find the difference between the reactants and products to find the energy of reaction, then use relationship: ln K = (-grxn)/(R*T) where K is your equilibrium constant, T is your temperature, and R is the gas constant with appropriate units. If I have data for the standard state, and want to calculate the energy of formation for a different temperature, how do I do this? I know I can adjust the equilibrium constant for temperature, but I'm wondering if it is possible to also calculate the energy of formation at a non standard temperature.
