10mg of an adsorbate gets adsorbed on a surface. This causes the release of 3J of heat at constant pressure and at 27^(ul@)C. [Molar mass of adsorbate = 100 g/mol]. (i) Find triangleH_("adsorption"). (ii) Argue whether the adsorption is physical or chemical ? (iii) If 20 mg of adsorbate is adsorbed at temperature T_(0). Then compare T_(0) and 27^(ul@)C :

Answer»

SOLUTION :`T_(0) lt 27^(ul@)C`
