Be sure to answer all parts. determine the overall orders of the reactions to which the following rate laws apply: (a) rate = k[no2]2 (b) rate = k zero order first order 1.5 order second order 2.5 order third order zero order first order 1.5 order second order 2.5 order third order (c) rate = k[h2][br2]1/2 (d) rate = k[no2]2[o2] zero order first order 1.5 order second order 2.5 order third order zero order first order 1.5 order second order 2.5 order third order

(a). second order.

(b). zeroth order.

(c). one and a half order.

(d). third order.

Explanation:

Hello,

In this case, you just have to add the concentration's powers in each rate law:

(a)

Just the 2-power is present, so it is a second order law.

(b)

No power is present, so it is a zeroth order law.

(c)

1 plus 1/2 gives 1.5, that is why it is a 1.5 (one and a half) order law.

(d)

2 plus 1 gives 3, that is why it is a third order law.

Best regards.
