Answer:
Explanation:
If an electron is in an excited state it can return to a lower energy level. When it does this, it loses energy. The amount of energy it loses will be equal to the difference in the energy levels it moves between. This energy is released as a photon.
Answer : The half-life of the reaction in seconds is, 244
Explanation :
The expression used for zero order reaction is:
![t_{1/2}=\frac{[A_o]}{2k}](https://tex.z-dn.net/?f=t_%7B1%2F2%7D%3D%5Cfrac%7B%5BA_o%5D%7D%7B2k%7D)
where,
= half-life of the reaction = ?
= initial concentration = 5.90 M
k = rate constant = 0.725 M/min
Now put all the given values in the above formula, we get:


conversion used : (1 min = 60 s)
Thus, the half-life of the reaction in seconds is, 244
