Questions and Answers

What is the primary reason Henry's Law is important in a gas dissolved in a liquid?

  • To understand the concept of Raoult's law
  • To determine the total pressure of the system
  • To explain the solubility of oxygen in water
  • To calculate the partial pressure of the dissolving gas (correct)

    • What is the result of the presence of a non-volatile solute B in a solution, according to Raoult's law?

  • It depends on the concentration of the solute B
  • It increases the vapor pressure of the solvent A
  • It has no effect on the vapor pressure of the solvent A
  • It lowers the vapor pressure of the solvent A (correct)

    • What is the unit of the constant K in Henry's Law?

  • mol/L
  • mmHg
  • atm-1 (correct)
  • L/mol
