A student calculated the number of moles of carbon dioxide to be 0.30 moles in a 200.0 g sample of a gaseous mixture. What is the percent composition of carbon dioxide? (molar mass = 44.01 g/mol) A. 0.066%
B. 13%
C. 30%
D. 6.6%

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.
