Explanation / Answer

1.

Do, (1) / (2)

1.54 * 10-5 / (3.07 * 10-5) = (6.56 * 10-2 / 0.131)n

0.502 = (0.501)n

n = 1

Therefore, order with respect to NO2- = 1

Now do ((1) / (3)

1.54 * 10-5 / (3.07 * 10-5) = (0.780 / 1.56)m

0.502 = (0.5)m

So, m = 1

Therefore, order with respect to NH4+ = 1

Over order of reaction = 1 + 1 = 2

Rate law expression can be written as,

Rate = k[NH4+][NO2-]

From (1)

1.54 * 10-5 = k(0.780)(6.56 * 10-2)

k = 3.01 * 10-4 M-1s-1
