WebbThe catalyzed reaction is thought to proceed by a two-step mechanism: H 2 O 2 + I- H 2 O + IO-(slow) IO-+ H 2 O 2 H 2 O + O 2 + I-(fast) a. Predict the rate law for the overall process Rate=k[H 2 O 2][I-] according to slow elementary step. However, I-is not consumed in the reaction and therefore changing its concentration does not impact rate. WebbThe two-step mechanism below has been proposed for a reaction between nitrogen monoxide and molecular chlorine: Step 1: NO ( g) + Cl 2 ( g) ⇌ NOCl 2 ( g) fast Step 2: NOCl 2 ( g) + NO ( g) 2NOCl ( g) slow. Use this mechanism to derive the equation and predicted rate law for the overall reaction.
