A student determines the value of the equilibrium constant to be 2.56x10^69 for the following reaction.
C(s,graphite) + O2(g) → CO2(g)
Based on this value of Keq:
ΔG° for this reaction is expected to be (greater, less) ____ than zero.
Calculate the free energy change for the reaction of 2.13 moles of C(s,graphite) at standard conditions at 298K.
ΔG°rxn = ____ kJ.
