75. Calculate the change in the entropy of the process of exchange of carboxymethylcellulose with ions K (Na) at 300K, if 23 kJ of heat is released, and the increase in the Gibbs function is 0.66 kJ. What conclusions can be drawn about the direction of binding of carboxymethylcellulose with K (Na) ions? (-78.87(J/K)
