Presets

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

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