Build intuition for Keq, ΔG°′, Q, and Le Chatelier's principle by building your own reaction and exploring how it behaves under different conditions.
Reaction
Under standard conditions (T = 298 K), Keq and ΔG°′ are linked by ΔG°′ = −RT ln Keq. Drag either slider or type a value directly — the other follows.
Inside a cell, neither temperature nor concentrations sit at standard values. The free energy of the reaction depends on both — by the law of mass action, ΔGrxn = ΔG°′ + RT ln Q. Set the temperature, Keq, and the concentrations to see the actual driving force.
