How `Delta H, Delta S` and `Delta G` changes during adsorption ?

(a) Write a note of Dialysis. (b) What is the effect on Delta H and Delta S during the process of adsorption ? (c ) Give an example for heterogeneous catalysis.

Under which of the following conditions is the relation Delta H = Delta U + p Delta V valid for a closed system ?

If Delta H and Delta U are the changes in the enthalpy and internal energy when a liquid is converted into its vapours at temperature T, then :

A mixture of 2 moles of carbon monoxide and one mole of oxygen in a closed vessel is ignited to get carbon dioxide. If Delta H is the enthalpy change and Delta U is the change in internal energy, then

A reaction hos both Delta H and Delta S - ve. The rate of reaction
