Question

4 moles of a are mixed with 4 miles of b when 2 moles of c are formed at equilibrium the equilibrium constant is

Answer 1

Explanation:

A      +      B      ⇄      C      +       D

initial  -                4             4                0               0

at equilibrium    4-x          4-x             x=2           x=2

so final moles    2             2                  2              2

equilibrium constant

= [C][D] / [A][B] = [2][2] / [2][2] = 1
