H2SO4 + KHCO3 = H2O + CO2 + K2SO4

H_2SO_4 (sulfuric acid) + KHCO_3 (potassium bicarbonate) ⟶ H_2O (water) + CO_2 (carbon dioxide) + K_2SO_4 (potassium sulfate)

Balance the chemical equation algebraically: H_2SO_4 + KHCO_3 ⟶ H_2O + CO_2 + K_2SO_4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2SO_4 + c_2 KHCO_3 ⟶ c_3 H_2O + c_4 CO_2 + c_5 K_2SO_4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, S, C and K: H: | 2 c_1 + c_2 = 2 c_3 O: | 4 c_1 + 3 c_2 = c_3 + 2 c_4 + 4 c_5 S: | c_1 = c_5 C: | c_2 = c_4 K: | c_2 = 2 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_1 = 1 and solve the system of equations for the remaining coefficients: c_1 = 1 c_2 = 2 c_3 = 2 c_4 = 2 c_5 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | H_2SO_4 + 2 KHCO_3 ⟶ 2 H_2O + 2 CO_2 + K_2SO_4

K_c = ([H2O]^2 [CO2]^2 [K2SO4])/([H2SO4] [KHCO3]^2)

rate = -(Δ[H2SO4])/(Δt) = -1/2 (Δ[KHCO3])/(Δt) = 1/2 (Δ[H2O])/(Δt) = 1/2 (Δ[CO2])/(Δt) = (Δ[K2SO4])/(Δt) (assuming constant volume and no accumulation of intermediates or side products)
