20. The decomposition of dinitrogen pentoxide has the rate law: If the initial concentration rate- 0.080 min [N20s] of N2Os is 0.30 M, what is the concentration after 2.6 minutes? a. 00.37 M N20s N203 O2 b, 0.24 M c. 0.13 M d. 0.32 M 2NOCI 2NO C12. Suppose 1.0 mole of Noci is introduced into a 2.0-liter container at 300 K. Evaluate the half-life of the reaction. In A In A kt a. 3.6 x 104 s n A In 3- C. 2. b. 2.4 x 104 s c. 7.1 x 104 s d. 4.0 x 104 s In A I. In A. 1.4 12 Consider the following mechanism:

Explanation / Answer

21.

This is a second order reaction

initial [NOCl] = 1 mol/2 L = 0.5 M

half-life = 1/k[NOCl]

            = 1/2.8 x 10^-5 x 0.5

            = 7.1 x 10^4 s

Answer : c. 7.1 x 10^4 s
