Chemical Kinetics

Question

Wired Faculty App

For the decomposition of azoisopropane to hexane and nitrogene at 543 K, the following data are obtained.

t(sec)

P (mm of Hg)

0

35.0

360

54.0

720

63.0

Calculate the rate constant.

Solution

As we have given the data
Thus,

K = \frac{2.303}{t} \log \frac{p_{1}}{p_{2}} = \frac{2.303}{360} \log \frac{35}{54} = 2.20 \times 10^{- 3} 5^{1}
