For oxidation of iron, 4Fe(s) + 3O_(2)(g) rarr 2Fe_(2)O_(3) (s) entrop change is -549.4 J K^(-1)mol^(-1) at 298K. In spite of negative entropy change of this reaction, why is the reaction spontaneous? (Delta_(r ) H^(theta) for this reaction is -1648 kJ mol^(-1))

Answer»

SOLUTION :`DeltaS_("TOTAL") = +4980.6 JK^(-1) mol^(-1)`
