Total Gas Pressure
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.)

The solution explains how to get the answer using a few easy-to-understand equations.
Determining Partial and Total Pressure: Dimethyl Ether Example
The decomposition of dimethyl ether at 504 degrees Celsius is a first-order reaction with a half-life of 27.0 min.
(CH3)2O (g) ----> CH4 (g) + H2 (g) + CO (g)
(a) What will be the partial pressure of (CH3)2O (g) after 1.29 h if its initial partial pressure was 596 mmHg? (in mmHg)
(b) What will be the total gas pressure after 2.71 h? ((CH3)2O and its decomposition products are the only gases present in the reaction vessel.)
(in mmHg)
