For process under a set of condition, `DeltaS_("sys") lt 0 and DeltaS_("surr") lt0`. Will be process the spontaneous?

For a process, DeltaS_(sys)=-15J*K^(-1) . For what value of DeltaS_("surr") will the process be non-spontaneous?

{:("column"-1,"Column"-2),((A)(DeltaG_("system"))_(T.P) = 0,(p) "Process is in equilibrium"),((B)DeltaS_("system")+DeltaS_("surrounding") gt 0, (q)"Process is nonspontaneous"),((C)DeltaS_("system") +DeltaS_("surroumding") lt 0 , (r) "Process is spontaneous"),((D)(DeltaG_("system"))_(T.P) gt 0,(s)"System is unable to do useful work"):}

{:("column"-1,"Column"-2),((A)(DeltaG_("system"))_(T.P) = 0,(p) "Process is in equilibrium"),((B)DeltaS_("system")+DeltaS_("surrounding") gt 0, (q)"Process is nonspontaneous"),((C)DeltaS_("system") +DeltaS_("surroumding") lt 0 , (r) "Process is spontaneous"),((D)(DeltaG_("system"))_(T.P) gt 0,(s)"System is unable to do useful work"):}

A process is non-spontaneous when DeltaS_("total") lt 0 .

In a reversible process, Delta S_(sys) + Delta S_(surr) is

In the reaction DeltaS_(sys)=xJ*K^(-1) and DeltaS_("surr")=-yJ*K^(-1) . The reaction will be spontaneous if ______.
