What would be the rate of disappearance of oxygen, if the rate of formation of nitric oxide (NO) is `3.6xx10^(-3)"mol L"^(-1)s^(-1)` ?

Options

A. `4xx10^(-3)"mol L"^(-1)s^(-1)`
B. `4xx10^(-3)mol^(-1)L^(-1)s^(-1)`
C. `4.5xx10^(-3)"mol L"^(-1)s^(-1)`
D. `4.5xx10^(-3)mol^(-1)L^(-1)s^(-1)`

Answer

C

Explanation

Rate of reaction interms of `O_(2)` & NO
`=(-1)/(5)(Delta[O_(2)])/(Delta t)=(1)/(4)(Delta[NO])/(Delta t)`
Rate of disappearance of oxygen `= (5)/(4)` (rate of appearance of NO)
`= (5)/(4)xx3.6xx10^(-3)`
`=4.5xx10^(-3)"mol L"^(-1)s^(-1)`
