The reason as why it is impossible to get a mathematical solution for a single-component system containing four phases in equilibrium is to be stated. Concept introduction: The chemical potential is the energy absorbed or released in a chemical reaction or in phase transition. It is a form of potential energy and also called as partial molar free energy. It is the function of pressure and temperature. The degree of freedom is the parameter that defines a system. It cannot be negative or zero

How much energy (at constant temperature and pressure) must be supplied as heat to 10.0 g of chlorine gas (as Cl2) to produce a plasma composed of Cl- and Cl+ ions? The enthalpy of ionization of Cl(g) is +12575 kJ mol-1 and its electron gain enthalpy is -349 kJ mol-1. Hence identify the standardenthalpy of ionization of Cl- (g).
