A 1 M solution of glucose reaches dissociation equilibrium according to equation given below 6HCHOhArrC_(16)H_(12)O_(6). What is the concentration of HCHO at equilibrium constant is 6xx10^(22)

Answer»

`1.6xx10^(8)`M
`3.2xx10^(6)`M
`3.2xx10^(-4)`M
`1.6xx10^(-4)`M

Solution :`6HCHOhArrC_(6)H_(12)O_(6)` forward REACTION
`C_(6)H_(12)O_(6)hArr 6HCHO` backward reaction
`K_(2) = [(1)/(K_(1))]^(1//6)` , `K_(2) = [(1)/(6xx10^(22))]^(1//6)`
`K_(2) = 1.6xx10^(-4)` M
