Consider the following two-step mechanism for a reaction: NO2(g)+Cl2(g)→ClNO2(g)+Cl(g)Slow NO2(g)+Cl(g)→ClNO2(g)Fast 1)What is the overall reaction? Express your answer as a chemical equation. Identify all of the phases in your answer. 2)Identify the intermediates in the mechanism. 3)What is the predicted rate law?

Solutions

Expert Solution

NO2(g)+Cl2(g)-----------------------> ClNO2(g)+Cl(g) , slow

NO2(g)+Cl(g)--------------------------> ClNO2(g) , fast

overall reaction : 2 NO2(g) + Cl2(g) --------------------> 2 ClNO2(g)

intermediates = Cl

predicted rate law only depends on slow step in the mechanism

rate = k [NO₂] [Cl₂]
