Adsorption leads to decrease in
randomness (entropy).i.e. ∆S< 0 for the adsorption to occur, ∆G should be
-ve. We know that ∆G=∆H-T∆S if ∆S is -ve, T∆S is +ve. It means that ∆G will
become negative only when ∆H is -ve and ∆H>T∆S
Molecular formula: MSO4Cl.
6H2O .
Formation of white
precipitate with Barium chloride indicates that SO42-
ions are outside the coordination
sphere, and no precipitate with AgNO3 solution indicates that the Cl−
ions are inside the coordination sphere.Since the coordination number of M is
6, Cl− and 5 H2O are ligands, remaining 1 H2O molecular
and SO42- are in
the outer coordination sphere.
if number of close packed atoms =N; then,
The number of Tetrahedral holes formed = 2N
number of Octahedral holes formed = N
therefore N:2N = 1:2
k = A e –(Ea/RT)
ln k = ln A – (Ea/R)
(1/T)
this equation is in the
form of a straight line equatoion
y = c + m x
a plot of lnk vs 1/T is
a straight line with negative slope
