Abstract

Standard
Gibb’s
free
energy
formation
(∆G f 0 )
of
alkanes
in
gaseous
state
at
298.15
K
is
estimated
by
a
quantitative
correlationships
with
Kier’s
mole cular
connectivity
index
( 1 X v ),
Vander
waal’s
volume
(Vw),
electrotopological
state
index
(E)
and
refrac totopological
state
index
(R).
The
regression
analy sis
reveals
a
significant
linear
correlationships
of
st andard
free
energy
of
formation
(∆G f
0 )
with
these
parameters.
