Answer to Question #93973 in General Chemistry for genny

Question

Why does nitrogen diffuse faster at a higher temperature?

Answer 1

As you know, with increasing temperature, the speed of movement of particles (molecules) increases proportionally. So, first of all, this is due to an increase in the internal kinetic energy of particles.

Consequently, an increase in temperature entails an increase in the velocity of particles (in our case, nitrogen), and hence diffusion.
