For a spontaneous process,the correct statement is

The condition for a spontaneous process is ......

Let us consider a reversible reaction at temperature,$T$. In this reaction,both $\Delta H$ and $\Delta S$ were observed to have positive values. If the equilibrium temperature is $T_e$,then the reaction becomes spontaneous at:

If $900 \ J/g$ of heat is exchanged at the boiling point of water,what is the increase in entropy in $J \ K^{-1} \ mol^{-1}$?
