Question: At 1258C Kp 0 25 for the reaction 2NaHCO3 s Na2CO3 s

At 1258C, Kp = 0.25 for the reaction
2NaHCO3(s) ⇌ Na2CO3(s) + CO2(g) + H2O(g)
A 1.00- L flask containing 10.0 g of NaHCO3 is evacuated and heated to 125oC.
a. Calculate the partial pressures of CO2 and H2O after equilibrium is established.
b. Calculate the masses of NaHCO3 and Na2CO3 present at equilibrium.
c. Calculate the minimum container volume necessary for all the NaHCO3 to decompose.
