Answer #1

Chemical potential or partial molar free energy can be defined as potential energy which can be absorbed or released during chemical reaction.It may change during phase transition.

The chemical potential of substance in a mixture is defined as slope of free energy of the system with respect to a change in the number of moles of substance.

It is partial derivative of free energy with respect to the amount of the substance when all other substances concentrations in the mixture remaining constant at constant temperature.

At constant pressure chemical potential is the partial molar Gibbs free energy. At equilibrium the sum of chemical potentials is zero as the free energy is minimum.

Assume we know the Gibbs free energy of reaction for a chemical reaction taking place at 298 K. What additional thermodynamic information do we need to know to compute the equilibrium constant of the reaction (a) at 298 K and (b) at 350 K? (You may assume that no phase transitions take place in this temperature range.)

Partial molar volume and partial molar Gibbs energy do share something in common (because both are partial molar quantities). Are both terms constant with respect to composition? Why or why not? When you use these partial molar quantities, can temperature change? Explain. In a binary system, the chemical potential of one component is increased; what about the chemical potential of the other component? Up or down? Why? (hint: you should use an equation to rationalize your answer).
