Asked by Rosi

At what temperature will the following reaction happen spontaneously, given that ΔH=8.91×103J and ΔS= –219.20 J/K?
CaSO4(s) + 2HCl(g) → CaCl2(s) + H2SO4(l)
Answered by DrBob222
Calculate dH for the reaction and dS for the reaction.
Then dGrxn = dHrxn - TdSrxn
Set dGrxn = 0, substitute the values you have for dHrxn and dSrxn and solve for T.

not spontaneous
