[學科] 自由能 Gibbs Energy
Liquid sodium, Na(l), may be used as a coolant in future nuclear power plants.
(a) How much heat is required to melt 100. kg Na at 1 atm, starting from 298K?
(b) What are the entropy and free-energy changes accompanying the heating
process?
Assume the heat capacities are temperature independent.
Cp = 6.7 cal/K mol (定壓莫耳熱容量)
Tf = 370.9 K
ΔH(fus) = 0.62 kcal/mol (熔化熱)
I've already figured out the heat and entropy.
But I don't know how to calculate the free energy...
Seek for someone to help me..
