During the phase transition, at constant temperature, of a solid from ...
- Given, During the phase transition, at constant temperature, of a solid from one form to another, the change in molar volume, ΔVm = 1.0 cm3 mol-1 is independent of pressure.
- When the pressure is increased from 1 bar to 3 bars is, from equation (2) we get
μ = Vmdp
μ = 1.0 cm3 mol-1 × (3 bar - 1 bar)
= 1.0 × 2 cm3. mol-1. bar
= 2 × 10-3 lit. atm. mol-1 (1cm3 = 10-3 lit and 1 atm = 1 bar)
= 2 × 10-3 × 102 J mol-1 (1 lit.atm = 100 J)
= 2 × 10-1J mol-1
μ = 1.0 cm3 mol-1 × (3 bar - 1 bar)
= 1.0 × 2 cm3. mol-1. bar
= 2 × 10-3 lit. atm. mol-1 (1cm3 = 10-3 lit and 1 atm = 1 bar)
= 2 × 10-3 × 102 J mol-1 (1 lit.atm = 100 J)
= 2 × 10-1J mol-1
Hence, The change in molar Gibbs free energy, in units of J mol-1, when the pressure is increased from 1 bar to 3 bars is 2 × 10-1J mol-1 .
