Dispersion of M:
the ratio of M number of irreversibly chemisorbed hydrogen atoms to the total number of M atoms
metal particle size:
irreversible H2 chemisorption using the relation d(chem)=5p/S
S is the metal specific surface area
p is the density of M
where
S_f = stoichiometry factor ____
V_ads = volume adsobed ____cm3/g
V_g = molar volume of gas at STP 22414 cm3/mol
m.w. = molecular weight of the metal ____ a.m.u.
%M = % metal ____ %
Thus
%D = ____ %
