H2SO4 + Na2CO3 = Na2SO4 + H2CO3

sulfuric acid + soda ash ⟶ sodium sulfate + carbonic acid

Balance the chemical equation algebraically: + ⟶ + Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 ⟶ c_3 + c_4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, S, C and Na: H: | 2 c_1 = 2 c_4 O: | 4 c_1 + 3 c_2 = 4 c_3 + 3 c_4 S: | c_1 = c_3 C: | c_2 = c_4 Na: | 2 c_2 = 2 c_3 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_1 = 1 and solve the system of equations for the remaining coefficients: c_1 = 1 c_2 = 1 c_3 = 1 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | + ⟶ +

K_c = ([Na2SO4] [H2CO3])/([H2SO4] [Na2CO3])

rate = -(Δ[H2SO4])/(Δt) = -(Δ[Na2CO3])/(Δt) = (Δ[Na2SO4])/(Δt) = (Δ[H2CO3])/(Δt) (assuming constant volume and no accumulation of intermediates or side products)
