Hg(NO3)2 = O2 + NO2 + Hg

Hg(NO_3)_2 (mercury(II) nitrate) ⟶ O_2 (oxygen) + NO_2 (nitrogen dioxide) + Hg (mercury)

Balance the chemical equation algebraically: Hg(NO_3)_2 ⟶ O_2 + NO_2 + Hg Add stoichiometric coefficients, c_i, to the reactants and products: c_1 Hg(NO_3)_2 ⟶ c_2 O_2 + c_3 NO_2 + c_4 Hg Set the number of atoms in the reactants equal to the number of atoms in the products for Hg, N and O: Hg: | c_1 = c_4 N: | 2 c_1 = c_3 O: | 6 c_1 = 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 = 2 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | Hg(NO_3)_2 ⟶ O_2 + 2 NO_2 + Hg

K_c = ([O2] [NO2]^2 [Hg])/[Hg(NO3)2]

rate = -(Δ[Hg(NO3)2])/(Δt) = (Δ[O2])/(Δt) = 1/2 (Δ[NO2])/(Δt) = (Δ[Hg])/(Δt) (assuming constant volume and no accumulation of intermediates or side products)
