C3H6 = H2 + C

C_3H_6 cyclopropane ⟶ H_2 hydrogen + C activated charcoal

Balance the chemical equation algebraically: C_3H_6 ⟶ H_2 + C Add stoichiometric coefficients, c_i, to the reactants and products: c_1 C_3H_6 ⟶ c_2 H_2 + c_3 C Set the number of atoms in the reactants equal to the number of atoms in the products for C and H: C: | 3 c_1 = c_3 H: | 6 c_1 = 2 c_2 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 = 3 c_3 = 3 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | C_3H_6 ⟶ 3 H_2 + 3 C

cyclopropane ⟶ hydrogen + activated charcoal

K_c = ([H2]^3 [C]^3)/[C3H6]

rate = -(Δ[C3H6])/(Δt) = 1/3 (Δ[H2])/(Δt) = 1/3 (Δ[C])/(Δt) (assuming constant volume and no accumulation of intermediates or side products)
