Expert Answer
Let's suppose volume= 1 L
In this case, Number of moles=Concentration

State of equilibrium can be expressed as-
A space space space plus space space B space space rightwards arrow space space space space space space 2 C 2 space space space space space space space space space 3 2 minus x space space space space 3 minus x space space space space space space space 2 x space space space space space space space space space space space space space space space left parenthesis A t space e q u i l i b r i u m right parenthesis K equals fraction numerator left parenthesis 2 x right parenthesis squared over denominator left parenthesis 2 minus x right parenthesis left parenthesis 3 minus x right parenthesis end fraction 4 equals fraction numerator 4 x squared over denominator left parenthesis x squared minus 4 x plus 4 right parenthesis end fraction x equals 1 comma negative 6 x space c a n space n o t space b e space n e g a t i v e space s o space w e space w i l l space c o n s i d e r space x equals 1 M o l e space o f space C space a t space e q u i l i b r i u m equals space 2 cross times 1 equals 2 space
