Analysis of a hydrocarbon showed that is contained 14.4% hydrogen and 85.6% carbon by weight. What is its simplest (empirical) formula? Question 12 options:

CH

CH2

CH3

C2H3

C2H5

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.
