Which of the following statements is correct for the spontaneous adsorption of a gas

Answer»

`DELTAS` is positive and, THEREFORE, `DELTAH` should be NEGATIVE
`DeltaS` is positive and, therefore, `DeltaH` should also be HIGHLY positive
`DeltaS` is negative and, therefore, `DeltaH` should be highly positive
`DeltaS` is negative and therefore, `DeltaH` should be highly negative

Solution :For adsorption `DeltaS=-ve, DeltaH=-ve`.
