Use the References to access important values if needed for this question. Dinitrogen tetraoxide is a colorless gas that dissociates into nitrogen dioxide, a reddish brown gas. N204 (g) 2 NO2 (g) An experiment was run to demonstrate that this is a dynamic equilibrium. Starting with a special form of N204 where one of the oxygens was isotopically labeled so instead of 16o),the system was then allowed to reach equilibrium. N-N Indicate with Y (yes) or N (no) which ofthe substances below show that the forward or reverse reactions occur for this chemical system.Explanation / Answer
In the forward reaction, NO2 is produced from N2O4. One of this NO2 molecule conatains O-18 another contains normal O. In the backward reaction two NO2 joins to form N2O4. Now, during reverse reaction, combination could be labeled-unlabeled, lebelebd-lebeled, unlabeled-unlabeled.
A. yes during reverse reaction ,unlabeled-unlabeled
B. No Two labeled O-18 are attached to one N
C.yes formed during forwards reaction
D : yes, during reverse reaction. labeled -unlabeled
