Chemistry: Delta Systems
The element cesium (Cs) freezes at 28.4?, and its molar enthalpy heat of fusion
is AHfus=2.09 Kj/mol
Calculate the value of Delta S total when 15.0 g of Cs(l) solidifies at 28.4 C
S Cs(s)=85.15 J
S Cs(l)=92.07 J
When molten cesium solidifies to Cs (s) at its normal melting point, is Delta system positive or negative?
