3. A reaction of the type X → Y + Z has a rate constant k = 3.6 x 10-5 M/s. Determine molarity of x after a reaction time of 30.0 min if the initial concentration of x is
0.096M
(3 marks)

0.16 M.

Explanation:

Hello!

In this case, since the reaction can be determined as zeroth-order because of the units of M/s, we can write the rate law as:

In such a way, since we need the initial concentration of X, we proceed as follows:

So we plug in to obtain:
