Chemical Engineering Thermodynamics Number of components (C), phase (P) and degrees of freedom (F) are related by Gibbs phase rule as F = C - P - 2 P + F - C = 2 C = P - F + 2 P = F - C - 2 F = C - P - 2 P + F - C = 2 C = P - F + 2 P = F - C - 2 ANSWER DOWNLOAD EXAMIANS APP
Chemical Engineering Thermodynamics When liquid and vapour phases of one component system are in equilibrium (at a given temperature and pressure), the molar free energy is Replaced by chemical potential which is more in vapour phase More in vapour phase Same in both the phases More in liquid phase Replaced by chemical potential which is more in vapour phase More in vapour phase Same in both the phases More in liquid phase ANSWER DOWNLOAD EXAMIANS APP
