The reduction of butanoic acid can form butanal and butan-1-ol. The boiling points of these compounds are shown in Table 1 below. Table 1-Boiling points of butanyl- compounds. Boiling Point (°C) Compound butan-1-ol 120 75 164 bir butanal butanoic acid f) 15.00 mL of 0.200 mol/L butanoic acid is titrated with 12.50 mL of NaOH until the equivalence point is reached. Determine the pH of the final titrated solution. (Ka = 1.51 x 10¹5) /4T] g) A series of reduction experiments was carried out at a given temperature. The results are summarized in Table 2 below. Determine the rate law expression for this reaction.
