Question

please answer with step by step detailed explanation correct option is given

Answer 1

Hope u can understand my words
==============================
In the equation,
2 N2O5 ===> 4NO2 + O2

It can be clearly stated that 2 mole of N2O5 produces 4 mole NO2 and 1 mole O2

Thus, 1 mole N2O5 produces nearly 2 mole NO2 and 0.5 mole O2.
__________________________
Thus going through the options...
--------------------------------------------------
1) incorrect.
Since,
1 mole of O2 is produced by 2 mole of N2O5..
And, 4 mole of NO2 is produced by 2 mole of N2O5
i.e. Rate of disappearance of N2O5 is twice times the rate of formation of O2. And half the times of NO2. i.e. Rate of formation of NO2 is four times the rate of formation of O2
_____________________________
2) incorrect.
Since,
1 mole N2O5 can give 2 mole NO2. i.e..
Rate of formation of NO2 is twice than the rate of disappearance of N2O5.
Or can say,
rate of disappearance of N2O5 is half times the rate of formation of NO2.
____________________________
3) correct.
Since,
1 mole O2 is produced by 2 mole N2O5
i.e.
Rate of disappearance of N2O5 is twice the rate of formation of O2.
Or can say,
Rate of formation of O2 is half times (0.5) the rate of disappearance of N2O5.
__________________________
4) incorrect..
Since,
Reason similar to reason number (2).
