Answer : It takes time for the concentration to decrease to 0.100 M is, 22.4 s
Explanation :
Formula used to calculate the rate constant for zero order reaction.
The expression used is:
![\ln [A]=-kt+\ln [A_o]](https://tex.z-dn.net/?f=%5Cln%20%5BA%5D%3D-kt%2B%5Cln%20%5BA_o%5D)
where,
![[A_o]](https://tex.z-dn.net/?f=%5BA_o%5D)
= initial concentration = 0.537 M
![[A]](https://tex.z-dn.net/?f=%5BA%5D)
= final concentration = 0.100 M
t = time = ?
k = rate constant = 0.075 M/s
Now put all the given values in the above expression, we get:
Therefore, it takes time for the concentration to decrease to 0.100 M is, 22.4 s
Answer:
The answer to your question is the first option
Explanation:
Just remember that to balance using this method,
first look for the elements that change their oxidation number, and
later count the number of electrons that changed,
later identify which element oxidazes and which reduces and
finally cross the number of electrons that change in each semireaction and write these numbers in the main reaction.
2Cr⁺³ (aq) + 6Cl⁻ (aq) ⇒ 2Cr(s) + 3Cl₂ (g)
2 Cr 2
6 Cl 6
