Question

What are the chemical potential, molalities, and activities of ionic solutions?

a) Chemical potential - energy stored in chemical bonds; Molalities - concentration in moles of solute per kg of solvent; Activities - reaction rates.
b) Chemical potential - partial molar free energy; Molalities - concentration in moles of solute per kg of solvent; Activities - effective concentrations.
c) Chemical potential - heat released during a reaction; Molalities - mass of solute per volume of solvent; Activities - ion charge.
d) Chemical potential - entropy change; Molalities - molarity of the solution; Activities - reaction equilibrium.

Answer 1

Chemical potential is the energy stored in chemical bonds, molality is concentration in moles per kilogram, and activities are effective concentrations.

Step-by-step explanation:

The chemical potential is the partial molar free energy of a substance, representing the energy stored in chemical bonds. Molality is the concentration of solute in moles per kilogram of solvent. Activities are a measure of the effective concentrations of species in a solution.

In summary, the chemical potential represents the energy stored in chemical bonds, molality is the concentration in moles per kilogram of solvent, and activities are the effective concentrations of species in a solution.
