<u>Answer:</u> The concentration of reactant after the given time is 0.0205 M
<u>Explanation:</u>
Rate law expression for first order kinetics is given by the equation:
where,
k = rate constant =
t = time taken for decay process = 11.0 min = 660 s (Conversion factor: 1 min = 60 s)
= initial amount of the reactant = 0.400 M
[A] = amount left after decay process = ?
Putting values in above equation, we get:
Hence, the concentration of reactant after the given time is 0.0205 M
