Question

For the reaction A + B â‡Œ C + D, Kc =
9 If A and B are taken in equal amounts, then amount of C at
equilibrium is :
(1) 1 (2) 0 25 (3) 0 75 (4) None of these

A + B ↔C +DInitial           1       1         -    -At eqm      1-x  1-x    x      xnv            1-x1   1-x1  x1  x1 KC = [C][D][A][B]9 = 1-x1-xx × x9x2= 1-2x+x21-2x-8x2 =0x= 0
25
Thus the amount of [C] = x = 0 25
Option 2 is correct

For the reaction A + B ⇌ C + D, Kc = 9. If A and B are taken in equal amounts, then amount of C at equilibrium is : (1) 1 (2) 0.25 (3) 0.75 (4) None of these

For the reaction A + B ⇌ C + D, K_c = 9. If A and B are taken in equal amounts, then amount of C at equilibrium is :
(1) 1 (2) 0.25 (3) 0.75 (4) None of these
