10% sites of a catalyst bed have adsorbed H2 (hydrogen gas) . On heating H2 gas is evolved from sitesites and collected at 0.03atm and 300K in a small vessel of 2.46cm3 . Number of sites available is 7.210 to the power 16 per cm2 and surface area is 1000cm2 .The number of surface sites occupied per molecule of H2 is (a) 1 (b) 2 (c) 3 (d)4 |
