Question 1

For the reaction 2N2O5(g) → 4NO2(g) + O2(g), the following data were collected:
 
t (minutes)
[N2O5] (mol/L)
 
0
1.24 × 10-2
 
10.
0.92 × 10-2
 
20.
0.68 × 10-2
 
30.
0.50 × 10-2
 
40.
0.37 × 10-2
 
50.
0.28 × 10-2
 
 
70.
0.15 × 10-2

​

The half-life of this reaction is approximately:

 
Reference: Ref 12-10

​

​


◦ 15 minutes
◦ 18 minutes
◦ 23 minutes
◦ 36 minutes
◦ 45 minutes

Question 2

For the reaction A → Products, successive half-lives are observed to be 10.0 min and 40.0 min. The reaction follows the integrated rate law.
Reference: Ref 12-13

​

​


◦ [A] = –kt + [A]0
◦ ln [A] = –kt + ln [A]0
◦ = kt +
◦ = kt +
◦ None of these are correct.
