Calculate Qc for a non-equilibrium snapshot of A plus B reversibly forming C plus D. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.
Q_c = [C][D]/([A][B])

Activities are approximated by concentrations, all coefficients equal one, and Q needs a matching K to predict direction.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
