Question

A mechanism for the gas phase reaction of fluorine with chlorine dioxide that is consistent with the observed rate law is: step 1 slow: Fz+CIO, step 2 fast: F+CIO, FCIO, +F FCIO, (1) What is the equation for the overall reaction? Use the smallest integer coefficients possible. If a box is not needed, leave it blank. (2) Which species acts as a catalyst? Enter formula. If none, leave box blank: (3) Which species acts as a reaction intermediate? Enter formula. If none, leave box blank: (4) Complete the rate law for the overall reaction that is consistent with this mechanism. (Use the form k[A][B]"..., where 'l' is understood (so don't write it) for m, n etc.) Rate

Answer 1

That is , » Adding the two step8- t f clo2+ f t t clo +2+ clot ftclo, Canceling the same species on both sided sides [F2] + [2002] [2F (102] 2) Catalysts are the species which take part in the reaction but are not consumed. one 18 , step they in they are consumed ar and produced in the same amount in the subsequent steps sch species 3 you are no there can see, in the given reaction. ... No catalysts. 3) Intermediates are the species which are not initiall present but are produced in one step and consumed in the subsequent step in the same amount so that none of them are leftover as products. As we can see, there is one such species. That is F. e Intermediate is E 4) The rate of reaction is determined by the slowest step. The slowest step here is f2 + (102 FCloat .. Rate = k [fa] [10₂ ] . Coefficient of fa and I clor are l e
