Hello!
In this case, we can divide the problem in two steps:
1. Dilution to 278 mL: here, the initial concentration and volume are 1.20 M and 52.0 mL respectively, and a final volume of 278 mL, it means that the moles remain the same so we can write:
So we solve for C2:
2. Now, since 111 mL of water is added, we compute the final volume, V3:
So, the final concentration of the 139 mL portion is:
Best regards!
Answer:
It will take 3.3 s for [NOCl] to decrease to 0.042 M.
Explanation:
Integrated rate law for this second order reaction-
where, [NOCl] is concentration of NOCl after "t" time, is initial concentration of NOCl and k is rate constant.
Here, = 0.076 M, k = 3.2
and [NOCl] = 0.042 M
So,
or, t = 3.3 s
So, it will take 3.3 s for [NOCl] to decrease to 0.042 M.
