Unformatted text preview: Chemistry 120B SP11 Problem Set 7 Solutions Total: 50 points 1. (i) See handout on bspace. (ii) (0) is the change in free energy associated with moving one solute from octanol to water in the standard state. (iii) dG =- SdT + V dp + i i dN i The Maxwell relation we want is i T p, { N j } =- S N i T,p,N j 6 = i The RHS of this equation is just- S i . i T p, { N j } =- S i For the second part, use the chain rule to get i /T 1 /T p, { N j } = i + 1 T i 1 /T p, { N j } Switching derivatives, d 1 T =- 1 T 2 dT i /T 1 /T p, { N j } = i- T 2 T i T p, { N j } Use the relation you got in the first part of the problem to write i /T 1 /T p, { N j } = i + T S i There are two ways to differentiate G corresponding to these two expressions G = H- TS G = X i i N i Differentiating these w.r.t. N i at fixed T , p , and N j 6 = i G N i T,p,N j 6 = i = i = H N i T,p,N j 6 = i- T S N...
