Question
the reaction between NO2 and CO to produceNO and CO2 is believed to occur via two steps: step 1: NO2 + NO2 ---> NO + NO3 step 2: NO3 + CO ----> NO2 + CO2 the experimental rate law is rate = k(NO2)2 a) write the equation for the overall reaction b) identify the intermidiate c) what can you say about the relative rates of steps 1 and2? the reaction between NO2 and CO to produceNO and CO2 is believed to occur via two steps: step 1: NO2 + NO2 ---> NO + NO3 step 2: NO3 + CO ----> NO2 + CO2 the experimental rate law is rate = k(NO2)2 a) write the equation for the overall reaction b) identify the intermidiate c) what can you say about the relative rates of steps 1 and2?Explanation / Answer
a) add both equations 2NO2 + NO3 + CO = NO + NO3 + NO2 + CO2 remove redundancies NO2 + CO = NO + CO2 b) intermediate is NO3 (doesn't appear in overall) c) step 1 is the rate determining step, because the rate law isk*(NO2)^2, which is also the rate law of step 1. Step 2 has an intrinsically "faster" rate than step 1, although inpractice, step 1 limits the rate of step 2.
