    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?

    1) Knowing the equation:

    (see attached file for the equation)

    at 20oC
    T1 = 20 + 273.15 = 293.15 K
    t1 (time) = 64 ...
