H2SO4 + ZnO = H2O + ZnSO4

sulfuric acid + zinc oxide ⟶ water + zinc sulfate

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 and Zn: H: | 2 c_1 = 2 c_3 O: | 4 c_1 + c_2 = c_3 + 4 c_4 S: | c_1 = c_4 Zn: | c_2 = c_4 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: | | + ⟶ +

sulfuric acid + zinc oxide ⟶ water + zinc sulfate

K_c = ([H2O] [ZnSO4])/([H2SO4] [ZnO])

rate = -(Δ[H2SO4])/(Δt) = -(Δ[ZnO])/(Δt) = (Δ[H2O])/(Δt) = (Δ[ZnSO4])/(Δt) (assuming constant volume and no accumulation of intermediates or side products)
