Is the formation of CO2(g) from its elements endothermic or exothermic? Exothermic because the ΔH is negative.

Endothermic because the ΔH is negative.

Endothermic because the ΔH is positive.

Exothermic because the ΔH is positive.

explanation:

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.
