Question 1 The factors reducing the rate of diffusion are A Increased molecular weight Explanation Diffusion is the phenomenon where the solute molecules move from a high concentration to lower concentration At the end of diffusion solute concentration is equal in all parts of the solvent The movement of the solute molecules in the solvent is called Brownian motion The Brownian motion will decrease if the molecular weight of the solute increase Heavier molecules need more time to travel a certain distance compared to the lighter molecules As a result the rate of diffusion will decrease B Denser media Explanation See Answer
