Hint 1. How to approach the problem
The formula for Gibbs free energy is AGrxn = AHrxn - TASxn. In this problem, AHrxn,
ASTxn, and 3652 K are given to you.
Transcribed Image Text:Gibbs free energy (G) is a measure of the
spontaneity of a chemical reaction. It is the
chemical potential for a reaction, and is minimized
at equilibrium. It is defined as
G=H-TS
where H is enthalpy, T is temperature, and S is
entropy.
The chemical reaction that causes iron to corrode
in air is given by
4Fe +302
2Fe2O3
in which at 298 K, AH = - 1684 kJ and
ASixn = 543.7 J/K.
Part A
What is the standard Gibbs free energy for this reaction? Assume the commonly used standard reference
temperature of 298 K.
