Answer #1

In a study of the decomposition of nitrous oxide at 565 °C N20(g) →N2(g) + % O2(g) the following data were obtained: N,O], M

Explanation :

1)

half life at starting concentration is 1.81 = 663 s

half life at starting concentration is 0.905 = 1327 s

2)

average delta (1 / N2O) / delta t = 1/ 663 [1 / 0.905 - 1 / 1.81]

                                                      = 8.33 x 10^-4 M-1 s-1
