Question 33

Multiple Choice

A possible mechanism for the overall reaction Br2 (g) + 2NO (g) → 2NOBr (g)
Is
Step 1) NO (g) + Br2 (g) A possible mechanism for the overall reaction Br<sub>2</sub> (g) + 2NO (g) → 2NOBr (g) Is Step 1) NO (g) + Br<sub>2 </sub>(g) NOBr<sub>2</sub> (g) (fast) Step 2) NOBr<sub>2</sub><sub> </sub>(g) + NO (g) 2NOBr (slow) What is the rate determining step for this reaction? A) step 2 B) reverse of step 1 C) both steps 1 and 2 D) step 1 E) reverse of step 2 NOBr2 (g) (fast)
Step 2) NOBr2 (g) + NO (g) A possible mechanism for the overall reaction Br<sub>2</sub> (g) + 2NO (g) → 2NOBr (g) Is Step 1) NO (g) + Br<sub>2 </sub>(g) NOBr<sub>2</sub> (g) (fast) Step 2) NOBr<sub>2</sub><sub> </sub>(g) + NO (g) 2NOBr (slow) What is the rate determining step for this reaction? A) step 2 B) reverse of step 1 C) both steps 1 and 2 D) step 1 E) reverse of step 2 2NOBr (slow)
