Explanation:
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:
0.3097 moles of an nonionizing solute would need to be added.
Explanation:
Molal elevation constant = 
Normal boiling point of ethanol = 
Boiling of solution =
Moles of nonionizing solute = n
Mass of ethanol (solvent) = 47.84 g
Elevation boiling point:





n = 0.3097 mol
0.3097 moles of an nonionizing solute would need to be added.
