The chemical reaction that causes magnesium to corrode in air is given by 2Mg +O2---> 2MgO in which
\(\Delta Hrxn = -1204kJ\)
\(\Delta Srxn = -217.1 J/K\)
A) What is the Gibbs free energy for this reaction at 5546 ? Assume that and do not change with temperature.
B) At what temperature Teq do the forward and reverse corrosion reactions occur in equilibrium?
