WebHow the second law of thermodynamics helps us determine whether a process will be spontaneous, and using changes in Gibbs free energy to predict whether a reaction will be spontaneous in the forward or reverse direction (or whether it is at equilibrium!). Key points WebThe quantities work, , heat, , and changes in internal energy, , are the most useful for describing a thermodynamic system.If energy is added to the system and work is done on the system and are positive and have the opposite signs for heat leaving the system and work done by the system. These quantities are typically measured in units of joules (J) or …
