A 40.0 g sample of solid ammonium carbonate is placed in a closed evacuated 3.00 L flask and heated to 400 degrees C. It decomposes to produce ammonia, water and carbon dioxide according to the equation. (nh4)2co2 (double arrow) 2nh3+ h20+co2 The equilibrium constant, Kp, for the reaction is 0.295 at 400 degrees C.
A). Write the kp equilibrium constant expression for the reaction.
B). Calculate kc at 400 C
C). Calculate the partial pressure of NH3(g) at equilibrium at 400 C.
