Consider this reaction:

NH4OHaq+NH3aqH2Oaq

At a certain temperature it obeys this rate law.

rate

=1.27M1s1NH4OH2

Suppose a vessel contains

NH4OH

at a concentration of

0.890M

. Calculate how long it takes for the concentration of

NH4OH

to decrease TO

14.0%

of its initial value. You may assume no other reaction is important.

Round your answer to 2

2

significant digits.
