A 50.0 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.
D). Calculate total pressure inside the flask at equilibrium.
E). Calculate the number of grams of solid ammonium carbonate in the flask and equilibrium.
F). What is the minimum amount in grams of solid ammonium carbonate that is necessary to be placed in the flask in order for the system to come to equilibrium?
