Explanation / Answer

1.

Rate = d[X] / dt

r = [ (3.83 * 10-3) - (2.14 * 10-3) ] / 514.3

r = 3.27 * 10-6 M / s

r = 1.94 * 10-4 M / min

so the answer is (e)

2.

d. 1

since the power of X is one hence the order is one.

3.

(a) Expt 1 and 2 . Because conc. of B is same we cna measure the rate of reaction with respect ot A

4.

(c) Expt. (1) and (3)

5.

(c) Expt (2) and (3)
