Question

2. For the reaction of the ammonium ion with nitrous acid, the net reaction is

NH4+(aq) + HNO2(aq) → N2(g) + 2H2O(l) + H+(aq)

​

If the initial concentration of nitrous acid is 1.00 M and, after 17.8 s has elapsed, the concentration of nitrous acid has fallen to 0.72 M, what is the average rate of the reaction over this time interval?

a.

​–0.015 M/s

b.

​0.04 M/s

c.

​0.015 M/s

d.

​–0.04 M/s

e.

​0.096 M/s
