The reaction rate constant for a particular second-order reaction is 0.13 L/mol·s. If the initial concentration of reactiant is 0.26 mol/L, how many seconds will it take for the concentration to decrease to 0.13 mol/L?

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.
