For a spontaneous process, the correct statement(s) is

Answer»

`(Delta G_(system))_T,PGT 0`
`(Delta S_(system)) + (Delta S_(surr)) gt 0`
`(Delta S_(system))_T ,P LT 0`
`(Delta U_(system))_T, V gt 0`

Solution :For a spontaneous process,
(i) `Delta G_(system) lt 0`
(ii) `Delta G_("TOTAL") = Delta S_("univ") = Delta S_(sys) + Delta S_(surr) gt 0`
This is a king of the mathematical expression of the 2nd law of thermodynamics .
