Question

The decomposition of nitryl chloride takes place according to the following equation:
2 NO2Cl(g) → 2 NO2(g) + Cl2(g)
The following mechanism is proposed for this reaction:
NO2Cl(g) ⇄ NO2(g) + Cl(g)
NO2Cl(g) + Cl(g) → NO2(g) + Cl2(g)
Which rate laws are INCONSISTENT with the proposed mechanism, regardless of the relative rates of the two steps?
I. Rate = k[NO2Cl]
II. Rate = k[NO2Cl]2

A.

I only

B.

II only

✓ Correct
C.

Both I and II

D.

Neither I nor II
