C + FeO = Fe + CO

C (activated charcoal) + FeO (iron(II) oxide) ⟶ Fe (iron) + CO (carbon monoxide)

Balance the chemical equation algebraically: C + FeO ⟶ Fe + CO Add stoichiometric coefficients, c_i, to the reactants and products: c_1 C + c_2 FeO ⟶ c_3 Fe + c_4 CO Set the number of atoms in the reactants equal to the number of atoms in the products for C, Fe and O: C: | c_1 = c_4 Fe: | c_2 = c_3 O: | 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: | | C + FeO ⟶ Fe + CO

K_c = ([Fe] [CO])/([C] [FeO])

rate = -(Δ[C])/(Δt) = -(Δ[FeO])/(Δt) = (Δ[Fe])/(Δt) = (Δ[CO])/(Δt) (assuming constant volume and no accumulation of intermediates or side products)
