Input interpretation
Na (sodium) + NaNO_3 (sodium nitrate) ⟶ N_2 (nitrogen) + Na_2O (sodium oxide)
Balanced equation
Balance the chemical equation algebraically: Na + NaNO_3 ⟶ N_2 + Na_2O Add stoichiometric coefficients, c_i, to the reactants and products: c_1 Na + c_2 NaNO_3 ⟶ c_3 N_2 + c_4 Na_2O Set the number of atoms in the reactants equal to the number of atoms in the products for Na, N and O: Na: | c_1 + c_2 = 2 c_4 N: | c_2 = 2 c_3 O: | 3 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_3 = 1 and solve the system of equations for the remaining coefficients: c_1 = 10 c_2 = 2 c_3 = 1 c_4 = 6 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 10 Na + 2 NaNO_3 ⟶ N_2 + 6 Na_2O

Names
sodium + sodium nitrate ⟶ nitrogen + sodium oxide
Equilibrium constant
K_c = ([N2] [Na2O]^6)/([Na]^10 [NaNO3]^2)
Rate of reaction
rate = -1/10 (Δ[Na])/(Δt) = -1/2 (Δ[NaNO3])/(Δt) = (Δ[N2])/(Δt) = 1/6 (Δ[Na2O])/(Δt) (assuming constant volume and no accumulation of intermediates or side products)
