The Total solution for NCERT class 6-12
The reaction, CO(g) + 3H2(g)CH4(g) + H2O(g) is at equilibrium at1300 K in a 1L flask. It also contain 0.30 mol of CO, 0.10 mol of H2┬аand 0.02 mol of H2O and an unknown amount ofCH4┬аin the flask. Determine theconcentration of CH4┬аin the mixture. The equilibriumconstant,┬аKc┬аfor the reaction at the giventemperature is 3.90.
Let the concentration of methane atequilibrium be┬аx.
It is given that┬аKc┬а= 3.90.
Therefore,
Hence,the concentration of CH4┬аat equilibrium is 5.85 ├Ч 10тАУ2┬аM.
