Greenhouse gas `CO_(2)` can be converted to `CO(g)` by the following reaction
`CO_(2)(g)+H_(2)(g) rarr CO_(2)+H_(2)O(g)` , termed as water gas reaction.
A mixture of gases containing 35 vol% of `H_(2)`,45 vol.% of CO and 20 vol. % `H_(2)O` is heated to 1000K . What is the composition of the mixture at equilibrium?

Answer

`CO_(2(g)) + H_(2(g)) hArr CO_(g) + H_(2)O_(g)`
`{:( t=0,-,.35,.45,.2),(t=eq,x,.35+x,.45-x,.2-x):}`
`therefore ((45-x)(.2-x))/(x(.35+x))=.703`
On solving x=108
`therefore X_(CO)=.342, X_(H_(2))=.458, X_(H_(2)O) = 0.092, X_(CO_(2))=0.108`
