Mass Transfer Henry's law states that the Partial pressure of a component over a solution is proportional to its mole fraction in the liquid Partial pressure is equal to the product of the mole fraction and total pressure Vapour pressure is equal to the product of the mole fraction and total pressure Partial pressure of a component over a solution is proportional to the mole fraction in the vapour Partial pressure of a component over a solution is proportional to its mole fraction in the liquid Partial pressure is equal to the product of the mole fraction and total pressure Vapour pressure is equal to the product of the mole fraction and total pressure Partial pressure of a component over a solution is proportional to the mole fraction in the vapour ANSWER DOWNLOAD EXAMIANS APP
