Sodium carbonate, NaCO3 (s), can be prepared by heating sodium bicarbonate, NaHCO3 (s).
2NaHCO3(s) <--> Na2CO3(s) + CO2(g) + H2O(g) Kp=0.23 at 100 degree C
If a sample of NaHCO3 is placed in an evacuated flask and allowed to achieve equilibrium at 100 degree C, what will the total gas pressure be?
A. 0.46 atm
B. 0.96 atm
C. 0.23 atm
D. 0.48 atm
E. 0.11 atm
