BMB428 Dr. Song Tan Physical Chemistry with Biological Applications Fall 2007 1 Due Oct 18, 2007 1. Since we have proven that G for a reaction is related to whether the reaction is spontaneous, it is useful to know how G changes with temperature. Start with the equation d G = V d P – S d T. (a) What is G T P ? (b) Use your result from (a) to derive the following equation: G T S P = −∆ . Remember that G = G product - G reactant and that the equation you derived in part (a) applies to both products and reactants. G T just measures how G (which is G product - G reactant ) changes with respect to temperature. 2. Using the equation obtained in question 1 and the Gibbs-Helmholz equation (eqn 4.31), it is possible to derive the Van't Hoff equation: ln K T H RT eq P o = 2 (a) For a reaction with a positive
