Calculate deltah and deltas for the transformation pb s25, Ask an Expert

Academics

The standard entropy of pb(s) at 298.15K is 64.80JKmol. The normal melting point of lead is 327.4 degree and the enthalpy of fusion under these conditions is 4.770 klmol. The heat capacities for lead in KJmol are

Cp(s)= 22.13 + 0.01172T+9.6x10^4 T^-2
Cp(l) = 32.51 + 0.00301 T

Calculate deltaH and deltaS for the transformation pb (s,25 degrees) (arrow) pb(l,400 degrees). What is the standard entropy of pb(l) at 400 degrees?
