question

What is the effect on the absorption rate due to raising the totalpressure from 1 to 3atmin the following situations : (I) The absorption of methane from an air-methane mixture which has 15 percent CH_4 by volume. Pure water is used as the solvent. Assume the gas film offers the main resistance to diffusion. (II) The absorption of CH_4 from an air-CH_4 mixture which has 25 percent CH_4 by volume. A solution of CH_4 in water is employed as the solvent. The vapor pressure of methane over the solution is 0.17 atm.

options

  1. Pressure change increases absorption rate by 10 percent in the first case, and has no effect in the second case
  2. Pressure change increases the absorption rate in both cases
  3. Pressure change has no effect on the absorption rate in the first case, and decreases the absorption rate by 30 percent in the second case
  4. Pressure change decreases the absorption rate in both cases
  5. Pressure change increases absorption rate by 25 percent in the first case, and decreases it by 10 percent in the second case
  6. Pressure change causes a 50 percent gain in absorption rate in the first case, and has no effect in the second case
  7. Pressure change causes a 75 percent decrease in absorption rate in the first case, and a 50 percent increase in the second case
  8. Pressure change has no effect on the absorption rate in both cases
  9. Pressure change decreases absorption rate by 15 percent in the first case, and increases it by 200 percent in the second case
  10. Pressure change has no effect on the absorption rate in the first case, and causes a 126 percent gain in absorption in the second case
