Best answer
`2ICl(g) ltimplies I_(2)(g) + Cl_(2)(g)`
`{:(प्रारंभिक सांद्रता ,0.78,0,0),(साम्य पर सांद्रता ,0.78-x,x,x):}`
`therefore K_(C) = ([I_(2)][Cl_(2)])/([ICI]^(2))`
`0.14 =(x xx x)/(0.78 - 2x)^(2)`
`x^(2) = 0.14(0.78 -2x)^(2)`
`=0.292-0.748x`
`1.748x=0.292`
`x=0.167`
`[I_(2)]=[Cl_(2)]=0.167` M
`[ICl]=0.78 -(2 xx 0.167) = 0.446`M
