What is a spontaneous process? For the equilibrium A+2BhArrC DeltaH

1.	What is a spontaneous process? For the equilibrium A+2BhArrC DeltaH is +400kJ and DeltaS is +200JK^(-1) Calculate the temperature above the reaction becomes spontaneous?
Answer» SOLUTION :The PROCESS that takes place on its own without the ASSISTANCE of external agency is called SPONTANEOUS process. `DeltaG=DeltaB-TDeltaS` At EQUILIBRIUM `DeltaG=0` `TDeltaS=DeltaH` `T=(DeltaH)/(DeltaS)=(400J)/(200J//k)=(cancel(400)xx10^(3)cancel(J))/(cancel(360_(1))cancel(J)//k)` `T=2000K`
