Calculate Kp for CO + 2H2 to CH3OH(g) Equilibrium

[zorro]

Homework Statement

0.15 mole of CO is taken in a 2.5L flask is maintained at 705K along with a catalyst so that the folwing reaction takes place

CO + 2H2 ---> CH3OH(g)

Hydrogen is introduced till the total pressure of the system is 8.5atm at equilibrium and 0.08 mole of methanol is formed. Calculate Kp.

Homework Equations

The Attempt at a Solution

Here do we have to take any initial concentration of H2?
Or do we have to assume that there is no H2 present initially (only 0.15 mole CO)

 

[Borek]

No H₂ at first, only CO.
