Around 20% surface sites have adsorbed N_(2). On heating N_(2) gas evolved form sites and were collected at 0.001 atm and 298 K in a container of volume 2.46cm^(3) the density of surface sites is 6.023xx10^(14)cm^(-2) and surface area is 1000cm^(2) find out the number of surface sites occupied per molecule of N_(2).

Answer»

Solution : No. of SURFACE sites PER MOLECULE of `N_2= (" no. of surface sites used to adsorb "N_2 "on a surface AREA of" 1000 cm^2)/(" total no. of adsorbed molecules ")`
