The Correct Option is
Solution and Explanation
Step 1: From the data, doubling the concentration of \([NO]\) from 0.30 to 0.60 (while keeping \([O_2]\) constant) results in quadrupling the rate, indicating a second-order dependence on \([NO]\).
Step 2: Increasing \([O_2]\) concentration from 0.30 to 0.60 (while keeping \([NO]\) constant) doubles the rate, indicating a first-order dependence on \([O_2]\).
Step 3: The total order of the reaction is \(2 (NO) + 1 (O_2) = 3\).
Step 4: Thus, the total order is 3, and the order in \([O_2]\) is 1.
