At a certain temperature this reaction follows second-order kinetics with a rate constant of
2.90M^(-1)*s^(-1)
:
2HI(g)->H_(2)(g)+I_(2)(g)
Suppose a vessel contains
HI
at a concentration of
0.370M
. Calculate the concentration of
HI
in the vessel 3.50 seconds later. You may assume no other reaction is important. Round your answer to 2 significant digits.
