hello, im having trouble with this prob...

a gaseous mixture of 2.00 mole of CH4 and 1.00 mole of H2S gas was placed in an evacuated container which was then heated to and maintained at a temp. of 727 C.  when equalibrium was established in the gaseous reaction:

CH4 (g)  + 2H2S (g) ----> CS2 (g) + 4H2 (g)

the total pressure in the container was 0.92 atm and the partial pressure of the H2 was 0.20 atm.  what was the volume of the container?

would i use the ICE table for this?

[dexangeles]

is the reaction equation correct considering the question?

[Donaldson Tan]

use PV = nRT to work out the equilibirum concentration (n/V) of H2.

The ICE table will tell you the number of moles of each component in equilibirium in terms of x (x: mole of CH4 reacted to achieve equilibrium.

Using the data given two equations, we can express x and V in two independent equations.
