possible mechanism for the overall reaction Br2(g)+2NO(g)2NOBr(g) Step 1) NO(g)+Br2(g)k1k1NOBr2(g) (fast) Step 2) NOBr2(g)+NO(g)k22NOBr (sow) What is the rate determining step? Step 1 Step 2 Both steps The reverse of step 1 The reverse of step 2 Are there any intermediates in the above reaction? Yes, NO Yes, Br2 Yes, NOBr2 Yes, NOBr No, there is no intermediate formed What is the best representation of the rate law rateraterate=k[NNO][Br2]=k[NOBr2][NO]=k[NO2[Br2] None of the above are reasonable
