The entropy change at a high temperature TX where aluminium is
oxidized by oxygen is 335 JK-1mol-1. The standard state entropy is
-310.25 JK-1mol-1. Calculate TX if Tf = 900K and Hf = 10400 Jmol-1
Al.
Given:
Cp<Al2O3> = 105.19 JK−1mol−1,CpO2 = 31.6
JK−1mol−1,Cp<Al> = 27.8 JK−1mol−1 and
Cp{Al} = 32.5 JK−1mol−1.
