sweet-ann [11.9K]

Answer:

The rate of disappearance of $NO_2$ for this period is $-1.32\times 10^{-5} M/s$

Explanation:

Initial concentration of $NO_2$ = x = 0.0138 M

Final concentration of $NO_2$ = y = 0.00886 M

Time elapsed during change in concentration = Δt = 374 s

Change in concentration , $\Delta [NO_2]$ = y - x = 0.00886 - 0.0138 M = -0.00494 M

The rate of disappearance of $NO_2$ for this period is:

$\frac{\Delta [NO_2]}{\Delta t}=\frac{-0.00494 M}{374 s}=-1.32\times 10^{-5} M/s$
