Question

Report the value of K_p for the decomposition of ammonium carbonate at 25°C if the total pressure of the system was 0.116 atm.

Answer 1

Answer #1

(NH4)₂CO3 (s) ------------------------------> 2 NH3 (g) + CO2 (g) + H2O(g)

2x x x

total pressure = 2x + x + x = 4x

4x = 0.116

x = 0.029

Kp = PNH3^2 x PH2O x PCO2

Kp = (2x)^2 X (x) X (x)

Kp = 4 x^4

Kp = 4 x (0.029)^4

Kp = 2.83 x 10^-6

Ammonium iodide, a solid, decomposes to give NH3(g) and HI(g). At 406 °C, some NH4I(s) is placed in an evacuated container. A portion of it decomposes, and the total pressure at equilibrium is 1.08 atm. Extra NH3(g) is then injected into the container, and when equilibrium is reestablished, the partial pressure of NH3(g) is 1.27 atm.
