Study on the Correlativity Between the Partition Function and Standard Entropy of Cations in Solid Compounds

WANG Chao, FENG Chang-jun~* (Department of Chemistey, Xuzhou Normal University, Xuzhou, Jiangsu 221116)  
Based on the relationship between partition function and entropy in statisical thermodynamics for distinguishable particle system, the atomic weight(A_(r,i)) and the degeneracy (g~e_(o,i)) of ground state atom i have excellent correlativity with the standard entropies (S~θ_m, J·mol~(-1)·K~(-1)) of 70 cations in solid compounds: S~θ_m=-0.25+6.22(lnA_(r,i))~(1.4)-0.02(lng~e_(o,i))~2,R=0.9995. The calculated values of S~θ_m basically agree with the experiment values.
