2

If the reaction:

$A_2+2B \rightarrow 2AB$

Follows the mechanism:

$i. A_2 \rightarrow 2A$ (Slow)

$ii. 2A+2B \rightarrow 2AB$ (Fast)

3

If the reaction:

$A_2+2B \rightarrow 2AB$

Follows the mechanism:

$i. A_2+B \rightarrow A+AB$ (Slow)

$ii. A+B \rightarrow AB$ (Fast)

What is the rate order with respect to ?

4

The reaction

$2NO_2+F_2\rightarrow 2NO_2F$

Follows the mechanism:
