It outlines the roles of Gibbs free energy, enthalpy, and entropy in determining whether reactions are thermodynamically favorable. The Gibbs free energy equation predicts reaction direction under specific conditions. The equilibrium constant (K) describes a reaction's equilibrium position using concentrations or partial pressures.

It uses...This page explains the importance of multivariate calculus and partial differentiation in thermodynamics, focusing on 'active' variables, cross derivatives, and mixed second-order derivatives. It uses examples like the van der Waals equation to relate difficult-to-measure quantities to easier ones. The distinction between state functions and path functions is also addressed, highlighting how changes in thermodynamic quantities can be analyzed using total differentials and partial derivatives.
