NaOH + PbCl2 + NaClO = H2O + NaCl + PbO2

NaOH sodium hydroxide + PbCl_2 lead(II) chloride + NaOCl sodium hypochlorite ⟶ H_2O water + NaCl sodium chloride + PbO_2 lead dioxide

Balance the chemical equation algebraically: NaOH + PbCl_2 + NaOCl ⟶ H_2O + NaCl + PbO_2 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 NaOH + c_2 PbCl_2 + c_3 NaOCl ⟶ c_4 H_2O + c_5 NaCl + c_6 PbO_2 Set the number of atoms in the reactants equal to the number of atoms in the products for H, Na, O, Cl and Pb: H: | c_1 = 2 c_4 Na: | c_1 + c_3 = c_5 O: | c_1 + c_3 = c_4 + 2 c_6 Cl: | 2 c_2 + c_3 = c_5 Pb: | c_2 = c_6 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 = 2 c_2 = 1 c_3 = 1 c_4 = 1 c_5 = 3 c_6 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 2 NaOH + PbCl_2 + NaOCl ⟶ H_2O + 3 NaCl + PbO_2

K_c = ([H2O] [NaCl]^3 [PbO2])/([NaOH]^2 [PbCl2] [NaOCl])

rate = -1/2 (Δ[NaOH])/(Δt) = -(Δ[PbCl2])/(Δt) = -(Δ[NaOCl])/(Δt) = (Δ[H2O])/(Δt) = 1/3 (Δ[NaCl])/(Δt) = (Δ[PbO2])/(Δt) (assuming constant volume and no accumulation of intermediates or side products)
