1.

At the sublimation temperature, for the process CO_(2(s))rarrCO_(2(g))

Answer»

`DeltaH,DELTAS and DeltaG` are all positive
`DeltaH gt 0, DeltaS gt 0 and DeltaG lt 0`
`DeltaH lt 0, DeltaS gt 0 and DeltaG lt 0`
`DeltaHgt0, DeltaSgt0 and DeltaG=0`

SOLUTION :Since the process is at EQUILIBRIUM `DeltaG=0 " for "DeltaG=0`, they should be `DeltaH gt 0, DeltaS gt 0`.
