Question

If the instantaneous rate of appearance of NO₂(g) is 0.0400 M/s at some moment in time, what is the rate of

disappearance of N₂O₅ (g) in M/s?

• A. 0.02
• B. 0.01
• C. 0.04
• D. 0.08

Answer 1

Answer: (A)

0.02

Answer 2

N₂O₅ ® 2NO₂ + $\frac{1}{2}$O₂

$\frac{2N_{2}O_{5}}{1}$ = $\frac{R_{NO_{2}}}{2}$

= $\frac{.04}{2}$

= 0.02
