For the reaction 2NaHCO3 = Na2CO3 + CO2 + H20 a 5.00 gram sample of NaHCO3 is placed in an evacuated flask and the temperature is increased to 50 degrees celcius. What is the Total Gas Pressure in the flask at equilibrium? Kp=3.90 X 10-4 = (PCO2)(PH2O.)
In this question we see that they give a mass of the starting material, however this is misleading, because we know that not all of it will react. You are ...
The solution explains how to get the answer using a few easy-to-understand equations.
