The equilibrium constant K c at 298   K for the reaction A + B ⇌ C + D is 100   . Starting with an equimolar solution with concentrations of A , B , C and D all equal to 1 M , the equilibrium concentration of D is _____ × 10 - 2 M . (Nearest integer)
Correct answer
0
Step-by-step solution
K C = 1 + x 1 - x 2 = 100 = 1 + x 1 - x = 10 = 1 + x = 10 - 10   x 11   x = 9 x = 9 11 [ D ]= 1 + 9 11 = 20 11 = 1 . 818 = 1 . 82   M (   approx   ) ⇒ 182 × 10 - 2   M
