Question

At atmospheric pressure, Li2SO4 crystals undergo a phasetransition from a “monoclinic” to a “cubic” structure at 590°C. Atthe transition,ΔV = 3.81cm3/mol and, ΔH=28.8 x 103 J/mol.If acrystal of Li2SO4 is deep under the ocean, at 800 atm, at whattemperature will it undergothe phase transition?
