Answer : It take time for the concentration to become 0.180 mol/L will be, 277.8 s
Explanation :
The integrated rate law equation for second order reaction follows:
![k=\frac{1}{t}\left (\frac{1}{[A]}-\frac{1}{[A]_o}\right)](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B1%7D%7Bt%7D%5Cleft%20%28%5Cfrac%7B1%7D%7B%5BA%5D%7D-%5Cfrac%7B1%7D%7B%5BA%5D_o%7D%5Cright%29)
where,
k = rate constant = 
t = time taken = ?
[A] = concentration of substance after time 't' = 0.180 mol/L
= Initial concentration = 0.360 mol/L
Putting values in above equation, we get:


Hence, it take time for the concentration to become 0.180 mol/L will be, 277.8 s

Answer:
Volume of box = 125 cm³
Explanation:
Given:
Length l = 10 cm
Width b = 5 cm
Height h = 2.5 cm
Find:
Volume of box
Computation:
Volume of box = lbh
Volume of box = 10 x 5 x 2.5
Volume of box = 125 cm³
The correct answer is that a pure substance cannot be physically broken down into different types of atoms.
