SUMMARY
The equilibrium constant (K) for the reaction 2NaHCO3(s) <--> Na2CO3(s) + H2O(g) + CO2(g) at 110.0 degrees C can be calculated using the total pressure of the gases at equilibrium, which is 1.648 atm. Since solid sodium bicarbonate has negligible vapor pressure, it is treated as a constant and does not appear in the equilibrium expression. The equilibrium constant will only include the partial pressures of the gaseous products, H2O and CO2, derived from the total pressure.
