Calculate the quantity of electricity obtained from 2 moles of electrons

Explanation:

Two moles of electrons is 2 faradays. 2 x 96500 coulombs give 24 dm3 H2 at rtp. So, if 2 x 96500 coulombs give 24 dm3 H2, work out what volume of hydrogen would be produced by 900 coulombs.

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.
