For a sample of CH3OH(g) is placed in the previously evacuated vessel with a pressure of P1 at 600 K, the final pressure in the vessel is
Pt=3P1
Generally, the Chemical reaction is given as
CH3OH----->CO +2H2
Therefore, The pressure P1 doubled at the product side of the reaction
In conclusion, the final pressure in the vessel at 600k
Pt=P1+P2
Pt=3P1
