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
TXn
in which at 298 K, AH
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.
Express your answer as an integer and include the appropriate units.
