Question
20. 2NaHCO3(s)
Na,CO3(s) + H20(g) + CO2(g), Kp(300 °C) = 1.55 atm², AH°rxn = +136 kJ
1) Write the formulas for Kp and Qp of this equation: Kp =
Qp =
2) A mixture of NaHCO3(s), Na2CO3(s) under 1.12 atm CO2(g) and 1.38 atm H20(g)
has Qp =
To reach equilibrium, it will shift to:
(show direction)
3) When a sample of NaHCo3(s) alone is heated in a sealed volume at 300 °C, it comes to
equilibrium with Kp(300 °C) = 1.55 atm?, Reg(CO2) =
atm, Peg(H20) =
atm,
and the total P =
atm.
4) If the mixture at equilibrium is compressed in volume by half at 300 °C, the total pressure at
the new equilibrium will be
atm
5) If the mixture at equilibrium is cooled, it will shift to:
(show direction). The total
pressure at the new equilibrium will be: higher ? lower ? same as before (circle one)
