SUMMARY
Total molar concentration remains constant in an isobaric isothermal system due to the equilibrium established between solid naphthalene and its vapor. The perfect gas equation (PV=nRT) indicates that while pressure (P) and temperature (T) are constant, the volume (V) can change, leading to variations in the number of moles (n). However, as n changes, total molar concentration remains constant at a value of 1, as the system adjusts to maintain equilibrium. The relationship C=CA+CB holds true under these conditions, confirming the constancy of total molar concentration.
