Question

1. Consider this reaction and the following data table for this reaction
  
  
2N ₂O ₅-->4NO ₂+ O ₂
  
The following data table shows the decrease in N ₂O ₅  concentration with time at 25 ^oC.  
  
Time (s)                      concentration N ₂O ₅ , M
0.000                          0.124
10.00                          0.110
20.00                          0.0880
30.00                          0.0730
40.00                          0.0540
  
Use the table to calculate the average rate of reaction between 10s and 30 s.

		0.114 x 10-2 M/s
		258 M/s
		0.905 M/s
		0.538 x 10-2M/s
		0.567 M/s
		3.05 x 10-1 M/s
		9.25 x 10-4 M/s
		9.60 x 10-4M/s
