Average rate of reaction for the following reaction, `2SO_(2)(g)+O_(2)(g)rarr2SO_(3)(g)` is written as

Options

A. `(Delta [SO_(2)])/(Delta t)`
B. `-(Delta [O_(2)])/(Deltat)`
C. `(1)/(2) (Detla [SO_(2)])/(Delta t)`
D. `(Delta [SO_(3)])/(Delta t)`

Answer

B

Explanation

Average Rate `=-(1)/(2) ([SO_(2)])/(Delta t) =-(Delta [O_(2)])/(Delta t) `
`=(1)/(2) (Delta [SO_(3)])/(Delta t) `
