KOH + KClO3 + KFeSO4 = H2O + K2SO4 + KCl + K2FeO4

KOH potassium hydroxide + KClO_3 potassium chlorate + KFeSO4 ⟶ H_2O water + K_2SO_4 potassium sulfate + KCl potassium chloride + K_2FeO_4 potassium ferrate(VI)

Balance the chemical equation algebraically: KOH + KClO_3 + KFeSO4 ⟶ H_2O + K_2SO_4 + KCl + K_2FeO_4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 KOH + c_2 KClO_3 + c_3 KFeSO4 ⟶ c_4 H_2O + c_5 K_2SO_4 + c_6 KCl + c_7 K_2FeO_4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, K, O, Cl, Fe and S: H: | c_1 = 2 c_4 K: | c_1 + c_2 + c_3 = 2 c_5 + c_6 + c_7 O: | c_1 + 3 c_2 + 4 c_3 = c_4 + 4 c_5 + 2 c_7 Cl: | c_2 = c_6 Fe: | c_3 = c_7 S: | c_3 = c_5 Since the coefficients are relative quantities and underdetermined, choose a coefficient to set arbitrarily. To keep the coefficients small, the arbitrary value is ordinarily one. For instance, set c_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 6 c_2 = 1 c_3 = 3 c_4 = 3 c_5 = 3 c_6 = 1 c_7 = 3 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 6 KOH + KClO_3 + 3 KFeSO4 ⟶ 3 H_2O + 3 K_2SO_4 + KCl + 3 K_2FeO_4

rate = -1/6 (Δ[KOH])/(Δt) = -(Δ[KClO3])/(Δt) = -1/3 (Δ[KFeSO4])/(Δt) = 1/3 (Δ[H2O])/(Δt) = 1/3 (Δ[K2SO4])/(Δt) = (Δ[KCl])/(Δt) = 1/3 (Δ[K2FeO4])/(Δt) (assuming constant volume and no accumulation of intermediates or side products)
