the two reactants react in equal amounts to give two products in equal amounts
let x = concentration of each product
Kc = 0.85 = [x]^2 / [1.00 - x]^2
.85 - 1.7 x + .85 x^2 = x^2
.15 x^2 + 1.7 x - .85 = 0
use quadratic formula to find x
moles = concentration * vessel size
For the following reaction
Co(g)+H2o(g)=Co2(g)+H2(g)
If the initial concentrations of Co and H2o are 1.00 mol in a 50 L vessel, what is the number of mole of each species at equilibrium, if the equilibrium constant Kc= 0.85 at 1000 C?
please can any one explain how to do this ?

should I use 1mole/50L =0.02 M instead of using 1 ?
Yes, you should use 1/50, calculate as shown above but x will be concentration and not mols. Then convert x = concentration in mols/L to mols.
