An ammonia plant operates at close to 700K and a Kp of 3.5 x 10-4 employing the stoichiometric ratio of 1:3 N22. If the equilibrium partial pressure of NH3 is 50. atm, calculate the partial pressures of the reactants and the total pressure. The suggestion is made that, since the [NH3] is cubed in the reaction quotient, the plant could produce the same amount of ammonia if the reactant ratio were 1:6 - and at a lower pressure and increased profitability. Calculate the partial pressure of each reactant and the total pressure under these new conditions assuming PNH3 is still 50. atm at equilibrium. Is the suggestion valid? Since when is NH3 cubed? What do we have to do? I don't understand anything. What is the 1:6 ratio? How do we prove improved profitability?
