First order rate law examples
WebExample Questions for Determining Rate Law From Elementary Steps Write the rate law for the following reaction given the reaction mechanism elementary steps: 2NO 2 (g) + F 2 (g) → 2NO 2 F (g) NO 2 + F 2 → NO 2 F + F (slow) F + NO 2 → NO 2 F (fast) Explanation: Since step 1 is the slower step, it is the rate-determining step for this reaction. WebThis reaction appears as second order but is first order, as water does not have any effect on rate. Additionally, Hydrolysis of Ester also appears to be second order but water (H 2 O) does not show any effect on rate so it is a good example for pseudo first order reaction. Hydrolysis of Ester. CH 3 COOC 2 H 5 + H 2 O → CH 3 COOH + C 2 H 5 OH
