Question

N2O5 is completely decomposed on heating. if 2 moles of N2O5 are decomposed then vol of O2 produced at R.T.P will be :

a. 2 x 24 litres
b. 5 x 22.4 litres
c. 4 x 24 litres
d. 5 x 24 litres

explain clearly i want conceptual understanding plz

Answer 1

It depends on HOW it decomposes.
The decomposition of \(N_2O_5\) takes place as so:
N2O5(g) -> 2NO2(g) + 1/2 O2(g)

Thus 2 moles of N2O5, decomposed would form,

2N2O5 -> 4NO2 + O2

Thus, 2 moles of N2O5 forms 1 mole O2
Thus, as 1 mole of O2 at RTP has volume of 24 liters, the answer must be 24 liters.

Answer 2

there is no answer as 24 liters in options ..
