Urea (NH2CONH2), an important nitrogen fertilizer, is produced industrially by the reaction
Given that ΔG∘ = -13.6 kJ, calculate ΔG at 25 ∘C for the following sets of conditions.
a) 50 atm NH3, 50 atm CO2, 1.0 M NH2CONH2
b) 0.10 atm NH3, 0.10 atm CO2, 1.0 M NH2CONH2
c) Is the reaction spontaneous for the conditions in part (a) and/or part (b)?
