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:
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:
1) pentane is of higher Molecular mass than propane hence heavier member
2) due to intermolecular hydrogen bonding methanol is liquid having lower molecular weight
3) I) in methanol C = sp3
ii) in methanoic acid C= sp2
5)I) i) The two carbon-oxygen bonds in the methanoate anion, HCO2-, have the same length due to resonance stabilization of the C-O bond
