059 – Using Gibbs Free Energy
In this video Paul Andersen explains how you can use the Gibbs Free Energy equation to determine if a process is spontaneous or not spontaneous. If the ΔG is less than zero the process is spontaneous. If the ΔG is greater than zero the process is not spontaneous. If the ΔG is equal to zero the process is at equilibrium. The ΔH, ΔS, and T are all used to calculate ΔG.
