For the reaction, `N_2O_5(g) rarr 2NO_2(g)+1//2O_2(g)`, the value of rate of disappearance of `N_2O_5` is given as `6.25xx10^(-3) "mol L"^(-1)s^(-1)`. The rate of formation of `NO_2 and O_2` is given respectively as

A

`6.25 xx 10^(-3) mol L^(-1) s^(-1)` and `6.25 xx 10^(-3) mol L^(-1) s^(-1)`

B

`1.25 xx 10^(-2) mol L^(-1) s^(-1)` and `3.125 xx 10^(-3) mol L^(-1) s^(-1)`

C

`6.25 xx 10^(-3) mol L^(-1) s^(-1)` and `3.125 xx 10^(-3) mol L^(-1) s^(-1)`

D

`1.25 xx 10^(-2) mol L^(-1) s^(-1)` and `6.25 xx 10^(-3) mol L^(-1) s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`(d)/(dt)[NO_(2)]=2 xx ((d)/(dt)[N_(2)O_(5)])=2 xx 6.25 xx 10^(-3)`
`=1.25 xx 10^(-2) mol L^(-1) s^(-1)` and
`(d)/(dt)[O_(2)]=(1)/(2)(d)/(dt)[NO_(2)O_(5)]=(1)/(2) xx 6.25 xx 10^(-3)`
`=3.125 xx 10^(-3) mol L^(-1) s^(-1)`
