The reaction in which urea is formed from NH3 and CO2 is shown below. The standard free-energy change G at 25◦C is −13.6 kJ/mol. 2NH3(g) + CO2(g) → NH2CONH2(aq) + H2O(l) a. Write an expression for the equilibrium constant, K, in terms of the molar concentrations of the reactants and products. b. Write an expression for the equilibrium constant, K, as a function of G◦ and temperature. c. Determine the value of the equilibrium constant, K, for this reaction at 25◦C.
