Slow step chemistry
WebbThe rate of the reaction is dictated by the slowest elementary step of the reaction. This step is called the “ rate-determining step “. No matter how fast the speed of the other elementary steps are, the reaction cannot go faster than the slowest step. The diagram above is called a reaction coordinate diagram or energy profile diagram. Webba) NOCl2 bc it's produced and consumed in the reaction b) Step 2. NOCl2 + NO —> 2NOCl bc it doesn't determine the rate of the overall reaction. Rate law for the overall reaction is …
