Gibbs free enrgy
Question | Answer |
---|---|
Symbol For Gibbs Free energy | G |
Units for Giibs free energy | J/mol |
conditions for gibbs free energy | const T,p |
Conditions for spontaneity for Gibbs energy | G<=0. |
equation for calculation G | G = H - TS |
Difference between first and second laws | First law:uses internal energy(U)to identify permissible change. Second law: uses entropy (S) to identify the spontaneous (irreversible) changes among the permissible change. |
