There is an increase in free energy due to interfacial energy is known as a capillarity effect or the Gibbs-Thomson effect. Find the increase in this free energy if the interfacial energy, the molar volume and the radius of the spherical particle are given as 10 (kJ/mm2), 6mm3/mol and 4mm respectively?

There is an increase in free energy due to interfacial energy is known as a capillarity effect or the Gibbs-Thomson effect. Find the increase in this free energy if the interfacial energy, the molar volume and the radius of the spherical particle are given as 10 (kJ/mm2), 6mm3/mol and 4mm respectively? Correct Answer 30 kJmol-1

This increase in the Gibbs free energy can be calculated using the formula G = (2γV)/r Hence substituting this value of interfacial energy, molar volume and radius in the equation we get the increase in energy as (2*10*6)/4 = 30 kJmol-1.
