Whichof thefollowingrateexpressiondoesnotrepresentthe rateof thereaction ? 2N_(2)O_(5(g)) to4NO_(2(g)) + O_(2(g))

Answer»

`-(1)/(2)(d[N_(2)O_(5)])/(dt)`
`(1)/(2)(d[N_(2)O_(5)])/(dt)`
`([O_2])/(dt)`
`(1)/(4) (d[NO_(2)])/(dt)`

SOLUTION :RATEOF reaction`=-(1)/(2) (d[N_(2)O_(5)])/(dt) `
`=+(1)/(4)(d[NO_(2)])/(dt ) =+ (d[O_(2)])/(dt)`
