KIO4 + KHSO3 = H2O + K2SO4 + I2 + KHSO4

KIO_4 potassium periodate + KHSO3 ⟶ H_2O water + K_2SO_4 potassium sulfate + I_2 iodine + KHSO_4 potassium bisulfate

Balance the chemical equation algebraically: KIO_4 + KHSO3 ⟶ H_2O + K_2SO_4 + I_2 + KHSO_4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 KIO_4 + c_2 KHSO3 ⟶ c_3 H_2O + c_4 K_2SO_4 + c_5 I_2 + c_6 KHSO_4 Set the number of atoms in the reactants equal to the number of atoms in the products for I, K, O, H and S: I: | c_1 = 2 c_5 K: | c_1 + c_2 = 2 c_4 + c_6 O: | 4 c_1 + 3 c_2 = c_3 + 4 c_4 + 4 c_6 H: | c_2 = 2 c_3 + c_6 S: | c_2 = c_4 + 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_3 = 1 and solve the system of equations for the remaining coefficients: c_1 = 2 c_2 = 7 c_3 = 1 c_4 = 2 c_5 = 1 c_6 = 5 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 2 KIO_4 + 7 KHSO3 ⟶ H_2O + 2 K_2SO_4 + I_2 + 5 KHSO_4

K_c = ([H2O] [K2SO4]^2 [I2] [KHSO4]^5)/([KIO4]^2 [KHSO3]^7)

rate = -1/2 (Δ[KIO4])/(Δt) = -1/7 (Δ[KHSO3])/(Δt) = (Δ[H2O])/(Δt) = 1/2 (Δ[K2SO4])/(Δt) = (Δ[I2])/(Δt) = 1/5 (Δ[KHSO4])/(Δt) (assuming constant volume and no accumulation of intermediates or side products)
