Chemical Reactions calculators
10 calculators Equilibrium Constant Calculator Calculate Kc or Kp for any reaction, convert between them, find delta G from K, and compare Q vs K to see which way the reaction runs.
Open Percent Yield Calculator Calculate percent yield or reverse-solve for actual or theoretical yield in mg, g, or kg. Supports moles mode, shows percent loss, and grades reaction efficiency.
Open Reaction Quotient Calculator (Qc and Qp) Calculate Qc (concentration-based) or Qp (partial-pressure-based) reaction quotient, compare to K, find logQ, and predict shift direction with step-by-step working.
Open Theoretical Yield Calculator Calculate theoretical yield in grams, kg, or lb from reactant mass or moles. Add actual yield to get percent yield instantly with step-by-step work shown.
Open Activation Energy Calculator Find activation energy from two rate constants and temperatures, or predict k at a new temperature. Arrhenius equation with step-by-step working and unit conversion.
Open Actual Yield Calculator Calculate actual yield, theoretical yield, or percent yield. Switch between grams and moles, see step-by-step working, and learn the chemistry behind reaction efficiency.
Open Arrhenius Equation Calculator Solve the Arrhenius equation for k, Ea, or k2 instantly. Three modes, step-by-step working, per-mole or per-molecule basis, and a live ln(k) vs 1/T plot.
Open Kp Calculator Calculate Kp, the equilibrium constant in terms of partial pressures. Convert Kc to Kp using temperature and delta-n, or enter partial pressures directly.
Open Molar Ratio Calculator Find the molar ratio between two substances, convert moles or masses using balanced equation coefficients. Step-by-step stoichiometry shown instantly.
