Carbon dioxide reacts with ammonia to give ammonium carbamate, a solid. The reverse reaction also occurs: CO2(g) + 2 NH3(g) 2NH4OCONH2(s) The forward reaction is first order in CO,g) and second order in NH3(g). Its rate constant is 0.238 atm¯² s-1 at 0.0°C (expressed in terms of partial pressures rather than concentrations). The reaction in the reverse direction is zero order, and its rate constant, at the same temperature, is 1.60 x 10-7 atm s1. Experimental studies show that, at all stages in the progress of this reaction, the net rate is equal to the forward rate minus the reverse rate. Compute the equilibrium constant of this reaction at 0.0°C.
