the differences in constraints of the carbons are less important solid carbon has an ordered, rigid structure with lttle freedom omotion of the individual carbon atoms. these carbons are less constrained in nonane and this would tend to make S morepositive and G more negative corresponding to an increase in K ( SEE EQUATIONS 4-2 Ang 4-3 ) however this is a small effect on S compared to the enomous difference un the degree of disorder of hydrogen between hydrogen gas and hydro bound to carbon in nonane negative entropy effect usually are obsered in ringclosure reactions such as the formation of cyclohexane from 1 -hexene which ocur wiht substantial loss of rotational freedom (disorder)about the c-c bonds
