A student is studying a chemical reaction that goes to completion in a beaker placed on a heated surface at a constant temperature. After the reaction has come to completion, the student removes the beaker from the heated surface and allows it to cool. Using the principles of non-equilibrium thermodynamics and irreversible processes, how can the student calculate the amount of heat that was transferred during the process? Specifically, what factors must be taken into account in order to accurately calculate the heat transfer?
