Question

The decomposition of dinitrogen pentoxide to nitrogen dioxide and oxygen
may be represented as follows:

2N2 O5=4NO2+O2
the concentration of N2O5, at a certaion moment is 5 moles/litre and after
half an hour becomes 2.6 moles/litre, find the rate of reaction in moles/
sec​

Answer 1

Answer:
