Equilibrium - Gas Pressure and Partial Pressure
Not what you're looking for?
In the manufacture of sodium carbonate, NaHCO3(s) is decomposed by heating.
2 NaHCO3(s) Na2CO3(s) + CO2(g) + H2O(g)
Kp=0.23 at 100 celsius.
1- If a sample of NaHCO3(S) is brought a temperature of 100 celsius in a closed container, what will be the total gas pressure(in atm) at equilibrium?
2- A mixture of 1.00 mol each of NaHCO3(s) and NaCO3(s) is introduced into a 2.50-L flask in which Pco2=2.10 atm and PH20(water)=715 mmHg. When equilibrium is established (at 100 celsius), will the partial pressures of CO2(g) and H2O(g) be greater than or less than their initial partial pressures? Explain please
3- Starting with the initial conditions of part(2), What will be the partial pressure of CO2(g) and the H2O(g) when the equilibrium is established at 100 celsius?
