The composition of an ideal gas mixture, by mass, is 25% nitrogen (N2), 25% carbon dioxide (CO2) and 50% oxygen (O2). The apparent gas constant of the mixture, in kJ/kg. K, is (write your answer with three decimal points; for example if the answer is 0.2876 kJ/kg. K write 0.288; if the answer is 0.2802 kJ/kg. K write 0.280; do not include the units in your answer)

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.
