Determining rate law with a fast initial step

WebSep 19, 2024 · A The rate law for step 1 is rate = k1 [NO 2] 2; for step 2, it is rate = k2 [N 2 O 4 ] [CO]. B If step 1 is slow (and therefore the rate-determining step), then the overall rate law for the reaction will be the same: rate = k1 [NO 2] 2. This is the same as the experimentally determined rate law. WebThe rate law for a reaction is the same as the rate law for the rate determining (slowest) step in the mechanism. The reaction in problem 6 is a good example. If the statement above was true, then the reaction would be second order with respect to ozone. tact air cargo solutions iata.org https://mcneilllehman.com

WebJan 17, 2024 · In fact, problems often are formatted along the lines of, "The mechanism for a reaction is {mechanism}. If {rate law} is the experimentally determined rate law, is this mechanism valid?" Since the overall rate law of a reaction must be found experimentally, it can be used to verify mechanisms.
