WebJul 6, 2024 · How does surface area affect diffusion rate? Surface area and thickness of the plasma membrane: Increased surface area increases the rate of diffusion, whereas a thicker membrane reduces it. Distance travelled: The greater the distance that a substance must travel, the slower the rate of diffusion. WebMar 26, 2024 · Surface area is not the only thing that influences the rate of evaporation. The temperature of the water also has an effect on the evaporation rate. Because hot water contains more energy than cold water, the rate at which molecules transition to the gaseous state increases proportionally with the temperature.
