Equilibrium constant K

Initial [A] (M)

Initial [B] (M)

For A + B ⇌ C + D, the reaction proceeds until the ratio of products to reactants equals K. A large K means products dominate; a small K means the reaction barely proceeds. The extent x is found by solving the equilibrium expression. Educational tool.

Extent of reaction x0.667

[A], [B] at eq.0.333, 0.333 M

[C], [D] at eq.0.667 M

Governing equation

K_{e q} = \frac{[ C ] [ D ]}{[ A ] [ B ]} = \frac{( 0.667 ) ^{2}}{( 0.333 ) ( 0.333 )} = 4

Reading this result: With K = 4, reactants and products coexist; the reaction proceeds to an extent x = 0.67.
