Part A In a particular experiment at 300 ∘C, [NO2] drops from 0.0138 to 0.00886 M in 374 s . The rate of disappearance of NO2 fo
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
