Question

For the first-order reaction 2N2O5 -> 2N2O4 + O2 at a particular temperature. The half-life of N2O5 is 0.90 hours. What fraction of the initial concentration of N2O5 will remain after 2.4 hours?

Answer 1

Answer: 1/4

Explanation:

2.4/0.09=2

1=1/2

2=1/4

3=1/8

So therefore because we got 2 , so it will be 1/4.
