When 25.5 grams of a molecular substance is dissolved in 225g benzene, the solution begins to freeze at -5.05C. Calculate the molar mass of this solute (I need to understand the work, and look at the image attached for the key for benzene.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
