Suppose that 4.9 mol no2 and 0.40 mol h2o combine and react completely. which reactant is in excess?

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.

distance, luminosity, brightness, radius, chemical composition, and temperature
