Q1.:

Initial Order Method:

1. For the reaction 2NO_(g)+CI_{2 (g)} $\to$2NOCI_​(g) the following date were collected. All the measurement were taken at 263K: 

Exp. No.	Initial [NO] (M)	Initial [CI2] (M)	Initial rate of disappearance  of CI2 (M/min)
1	0.15	0.15	0.60
2	0.15	0.30	1.20
3	0.30	0.15	2.40
4	0.25	0.25	?

(a) Write the expression for rate law.
(b) Calculate the value of rate constant and specify its units.
(c) What is the initial rate of disappearance of CI₂ in experiment 4?
