Adsorption of a gas on the surface of solid is generally accompanied by decrease in entropy. Still it is a spontaneous process. Explain |
| Answer» Solution :Adsorption is an exothermic PROCESS, i.e., energy factor favours the process. As `Delta G = Delta H - T Delta S` ,in adsorption, THOUGH `Delta S`is -ve but `Delta H`is also -ve and `Delta H GT T Delta S`in magnitude so that `Delta G`is -ve. Hence, the process is SPONTANEOUS | |
