Hello, I am looking for help and an explanation for part c of this problem. Assume that solutions of PhEt : PhH behave ideally. a) Calculate the entropy of mixing if 40 g of PhEt is mixed into 50 g of PhH. --> 5.57 J/K b) At room temperature (298K), what is delta G mix for mixing 40 g of PhEt and 50 f of PhH? --> -1.66 kJ c) Would you notice a temperature change associated with the process...
