What is the rate constant

Reference no: EM131025228

The gas-phase decomposition of NO2, 2 NO2(g)→ 2 NO(g) + O2(g), is studied at 383 °C, giving the following data:

Time (s)	[NO2] (M)
0	0.1
5	0.017
10	0.009
15	0.006
20	0.005

(a) Is the reaction first order or second order with respect to the concentration of NO2?

(b)What is the rate constant?

(c) If you used the method of initial rates to obtain the order for NO2, predict what reaction rates you would measure in the beginning of the reaction for initial concentrations of 0.200 M, 0.100 M, and 0.050 M NO2.
