Question

Starting with the definition of Gibbs free energy, the definition of enthalpy, the definition of entropy and the definition of work, show that dG=0 for a reversible process but dG<0 for an irreversible process.

Answer 1

to do wolk available 1. The energy Gibb's free enerzy (G): The energy ove for the system is called as Gibt's free energy (G). The Gibb's energy (G) is related to Enthalpy (#) and entropy (s) as G=H TS G is also called as Thermodynamic free energy. Enthalpy (H). A thermodynamic heat content ces the total heat content of a systemis called a Enthalpy CH) Enthalpy (H) is rel energy (E) and work done by the system (W) TH= E + PV thalpy (+) is related with Internal Entropy (5): A thermodynamic rmodynamic quantity quanto which inclicates the unavailability of to do work by the system is called as Gotropy is - Randomness of the system called Disorder (or) as Entropy (5) Work (W): According to Thermodynamics, work performed by a system is the energy transferred by the system to it's surroundings. W = pav] Reversible prow's. If a process is carried out in infinitesimal Changes then it is said to be in equillibrium At equillibrium, there is no change in free energy =) AG=0] IYYeversible prowess Foy an Irrevesible process TOS SOH AGE OH-TAS → PGLO
