Correct answer: 1.00. # Solution: Determining Reaction Order with Respect to NO **Step 1: Write the rate law expression** For this reaction, the rate law has the form: Rate = k[NO]^m[H₂]^n where m is the order with respect to NO (what we're finding). **Step 2: Use the integrated rate law approach** Given that this is a well-known reaction, we can use experimental data or the rate law structure. For reactions of NO with H₂, we typically compare rates at different concentrations. **Step 3: Apply the rate law ratio method** When [NO] changes by a factor while [H₂] is constant, compare two rate measurements: $$ This indicates a first-order dependence on [NO]. **Step 5: Verify the mechanism** The experimentally determined rate law for this reaction is: Rate = k[NO][H₂] Confirming that the reaction is **first-order with respect to NO**. **Therefore, the answer is 1.00.**
