Answer:

(a).

$order \: of \: A = 2 \\ order \: of \:B = 0 \\ rate = k[A] {}^{2} [B]$

(b)

$0.32 \times {10}^{ - 3} = k {(0.12)}^{2} (0.15) \\ k = 0.148 \: {mol}^{ - 2} {dm}^{6} {s}^{ - 1}$

While the extensive properties are those which vary with the variation in the quantity of the material.

Intensive properties:

Mass and volume

Extensive properties:

Density and melting point

Explanation:

The properties that do not vary with the variation in the quantity of the material are called as intensive property.

While the extensive properties are those which vary with the variation in the quantity of the material.
