Answer : The concentration of AB after 14.0 s is, 0.29 M
Explanation :
The expression used for second order kinetics is:
where,
k = rate constant =
t = time = 14.0 s
= final concentration = ?
= initial concentration = 1.50 M
Now put all the given values in the above expression, we get:
Therefore, the concentration of AB after 14.0 s is, 0.29 M
The answer is: [D]: a reactant.
