The equilibrium constant of the reaction...

The equilibrium constant of the reaction
`CO + H_2O iff CO_2 + H_2`
at 800 K is 4.12. A mixture of 20% CO and 80% `H_2O` is heated to 800 K. Determine the composition of the mixture in the state of equilibrium and the yield of hydrogen if 1 kg of water vapour is taken.

Text Solution

Verified by Experts

`CO - 1.447% , H_2O - 59.858%`
`CO_2 - 37.013%, H_2 - 1.68%`
