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. WebbSlope = -k Integrated Rate Law: Second Order 1/ [A]t = kt + 1/ [A]0 Slope = k Units of k: Zero Order M/s or Ms^-1 Units of k: First Order s^-1 Units of k: Second Order M^-1 * s^-1 Half Life Expression (First Order) t 1/2 = ln (2) / k Activation Energy (Ea) - minimum energy needed to reach the state where reactant molecules' bonds break

Webb14 mars 2024 · The slow step is the determining step that matches the rate law. For example in the 3/04 lecture, the NO2 + CO reaction had its slow step as the first … WebbThe rate law is determined by the slow step and would be: rate = k 2 [B][C] where k 2 is the rate constant for the second step in the mechanism. However, this rate law contains an … diamond resorts bent creek gatlinburg tn

WebbWe have 2 moles of NO so in the rate expression we will write it as NO to the power 2. With our H2 from the slow step, our rate expression should be rate= k (H2) (NO)^2. If you still unsure check a channel on youtube called “Popemup chemistry” for a more depth explanation in his topic 6/16 playlist. 3 Temporary_Working225 • 3 days ago 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 … WebbThis reaction involves a two-step mechanism. The first step is a relatively fast reaction in which a pair of NO molecules combine to form a dimer, N 2 O 2 . The product of this step … diamond resorts beaver creek
