Part A The rate constant for a second-order reaction is 0.13 M-15-1. If the initial concentration of reactant is 0.26 mol/L, it takes
to 0.09 mol/L
s for the concentration to decrease

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
