Question

Use the data below for the solubility of 1-butane in benzyl alcohol at 273K to calculate the Henry’s law constant for this gas.

Answer 1

Answer #1

Henry law states that the solubility of a gas in a liquid is directly proportional to the partial pressure of a gas over the liquid.

P = KH*X

KH = P/X

KH = henry law constant

P = partial pressure of 1-butane

X = solubility of 1-butane in benzyl alcohol

P /torr X 200 400 600 KH =P/X average 0.04 5000 0.087 4597.701 4112.197 0.151 3973.51 0.193 3626.943 0.226 3362.832 700 760

KH = henry law constant = 4112.2 torr

Calculate the rate constant, k, by using Equation 3 (k'=k[OH]^1). Keep in mind, the NaOH solution was diluted by 50% at the start of the experiment. Write a final generic rate law using Equation 1 (k[OH]^x[CV]^y) using the experimental determined values for k, and y. Find the average for CV (Crystal Violet) order (y), pseudo rate constant (k'=3.1x10^-8 Ms^-1), and the rate constant (k).
