Explanation:
Hello,
In this case, given the concentration of the potassium phosphate, we can compute the concentration of potassium ions by noticing that in one mole of salt, three moles of potassium ions are present. Moreover, since the molar units (mol/L) are in terms of potassium phosphate we should apply the following mole-mole relationship:
Best regards.

For
a first-order reaction, the rate law would be expressed as:<span>
r = dC / dt = -kC
Integrating it from time zero and
the initial concentration, Co, to time, t, and the final
concentration, C. We will obtain the first-order integrated law as follows:
ln C/Co= -kt
To determine the concentration of N2O in the system at a certain time, we simply substitute the given values from the problem statement
as follows:
</span>ln C / Co = -kt<span>
ln C / 10.9 = -0.76 (9.6)
e^ln C / 10.9 = e^-0.76 (9.6)
C / 10.9 = 6.78 x 10^-4
C= 7.39 x 10^-3 m
<span>
Therefore, the concentration of N2O in the system after 9.6 s would be 7.39 x10^-3 m.
