Question

Ozone decomposes to oxygen according to the equation 2O3 (g) ⟶ 3 O2 (g). Write the equation that relates the rate expressions for this reaction in terms of the disappearance of O3 and the formation of oxygen.

We’re being asked to write the rate expression in terms of a) the rate of disappearance of O3 and b) rate of formation of O2 for the following reaction: 2O3 (g) ⟶ 3 O2 (g).Recall that for a reaction aA → bB, the rate of a reaction is given by:Rate=-1aΔ[A]Δt=1bΔ[B]Δtwhere:Δ[A] = change in concentration of reactants or products (in mol/L or M), [A]final – [A]initialΔt = change in time, tfinal – tinitiala, b = stoichiometric coefficients from balanced equation[readmore]Using the general rate expression, we need to determine the stoichiometric coefficient from the given balanced equation.Let's start with O3:Since O3 is a reactant, the rate with respect to O3 is negative (–) since we’re losing reactants.The stoichiometric coefficient of O3 is 2.The rate of disappearance of O3 is:rate of disappearance, O3=-12·∆[O3]∆tFor O2:Since O2 is a product, the rate with respect to O2 is positive (+) since we’re gaining productsThe stoichiometric coefficient of O2 is 3.The rate of formation of O2 is:rate of formation, O2=+13·∆[O2]∆tThe equation for the rate expression for the given reaction is:rate =-12·∆[O3]∆t=+13·∆[O2]∆t
