. Carcinogenic nitrosamines are produed from amines such as dimethylamine and nitrous acid according to the following mechanism: HNO 2 + HNO 2 → H 2 O + N 2 O 3 (fast, reversible) (CH 3 ) 2 NH + N 2 O 3 → (CH 3 ) 2 NHNO + + NO 2 - (slow) (CH 3 ) 2 NHNO + + → (CH 3 ) 2 NNO + H + (fast) (b) What is the molecularity of each step?
