For the reaction NO(2)(g) + CO(g) to NO(...

For the reaction `NO_(2)(g) + CO(g) to NO(g) + CO_(2)(g)`, the experimentally determined rate expression at 40 K is:
rate =`k[NO_(2)]^(2)`
What is the proposed mechanism for the reaction?

Text Solution

Verified by Experts

According to available information, rate is proportional to the square of the molar concentration of `NO_(2)`. Therefore, the proposed mechanism for the reaction is:
`NO_(2) +NO_(2) overset(Slow)toNO+NO_(3)`
`NO_(3) + CO overset("Fast")to CO_(2) + NO_(2)`
