Which one of the following is not applicable to the phenomenon of adsorption?A. `Delta H gt 0`B. `Delta G lt 0`C. `Delta S lt 0 `D. `Delta H lt 0` |
|
Answer» Correct Answer - A For phenomenon of adsorption `Delta H lt 0` i.e., enthalpy change during phenomenon of adsorption is negative because during adsorption, there is always a decrease in residual forces of the surface which lead to decrease in surface energy which appears as heat. So, adsorption is an exothermic process and `Delta H lt 0`. |
