For the reaction at 500 (K) NO(2)(g)+CO(...

For the reaction at `500 (K)` `NO_(2)(g)+CO(g)^(*) rarr CO_(2)(g)+NO(g)` the proposed mechanism is as follows: i) `(NO)_(2)+(NO)_(2) rarr (NO)+(NO)_(3)` (slow) ii) `(NO)_(3)+(CO) rarr (CO)_(2)+(NO)_(2)` (fast) What is the rate law for the reaction?

Text Solution

Verified by Experts

Rate law `r=(k)[(NO)_(2)]^(2)` because slowest step determines the rate law.
