Consider two processes: sublimation of I2(s) and melthing of I2(s) Note: the latter process can occur at the same temperature but somewhat higher pressure). I2(s) -> I2(g) I2(s) -> I2(l) Is ΔS positive or negative in these processes? Sublimation: ΔS is positive, ΔS is negative Melting: ΔS is positive, ΔS is negative In which of the processes will the magnitude of the entropy change be greater? sublimation, melting
