Question

The gas phase reaction of carbon monoxide with nitrogen dioxide is believed to occur by the following mechanism: tep 1 slow: 2NO2NO+No step 2 fast: NO3 CO> NO2 + CO2 (1) What is the equation for the overall reaction? Use the smallest integer coefficients possible. If a box is not needed, leave it blank. 1 (2) Which species acts as a catalyst? Enter formula. If none, leave box blank: (3) Which species acts as a reaction intermediate? Enter formula. If none, leave box blank: (4) Complete the rate law for the overall reaction that is consistent with this mechanism. (Use the form k[A]"[B]n... , where '1' is understood (so don't write it) for m, n etc.)

Explanation / Answer

add all

2NO2 = NO3 + NO

NO3 + CO = NO2 + CO2

addition

2NO2 + NO3 + CO = NO2 + CO2+NO3 + NO

cancel commont erms

NO2 + CO = CO2+NO

Q2.

catalyst --> msut be NO2 since it is recovered at the end

intermediates must be produced and consumed

then

NO3 is produced, then consumed in step 2, this is intermediate

rate depends on slwoest step so

Rate = k*[NO2]^2
