Question
Consider this reaction mechanism: The overall reaction is order with respect to NO_2 and order with respect to Cl_2. 1^st, 1^st 1, ^st, 2^nd 2^nd, 1^st 2^nd, 2^nd What is the catalyst in this reaction mechanism? Which statement best explains why a catalyst increases the rate of a reaction? It provides an alternative mechanism with a lower activation energy. It makes the equilibrium constant for the reaction larger. It raises the temperature of the reaction mixture. It increases the concentration of the reactants.Explanation / Answer
(39) option (a) is correct. since in slow step (rate determinig step only one molecule of each NO2 and Cl2 involved
(40) option (d). since in net reaction Cl is not involved and also it initiates the first step of reactio.
(40) option (a) is correct. catalyst increases rate of reaction by lowering its activation energy. i,e reaction will proceed in different path way.
