For the reaction, 2 NO 2 ( g ) → 2 NO ( g ) + O 2 ( g ) , dt d [ NO 2 ] is 1.3 × 1 0 − 5 mol L − 1 sec − 1 , What is rate of O 2 ?

− 2 1 dt d [ NO 2 ] = dt d [ O 2 ] 2 1 ( 1.3 × 1 0 − 5 ) = dt d [ O 2 ] dt d [ O 2 ] = 6.5 × 1 0 − 6 L − sec mo 1

For the reaction, $2 NO_{2 (g)} \to 2 NO_{(g)} + O_{2 (g)}, \frac{d [ NO _{2} ]}{dt}$ is $1.3 \times 1 0^{- 5} mol L^{- 1} sec^{- 1}$ , What is rate of $O_{2}$ ?

Options:

Answer:

Solution:

$- \frac{1}{2} \frac{d [ NO _{2} ]}{dt} = \frac{d [ O _{2} ]}{dt} \frac{1}{2} (1.3 \times 1 0^{- 5}) = \frac{d [ O _{2} ]}{dt} \frac{d [ O _{2} ]}{dt} = 6.5 \times 1 0^{- 6} \frac{mo 1}{L - sec}$
