What effect will the number of particles and temperature have on the rate of diffusion of gas molecules?
a.
the rate of diffusion decreases with the increase in number of particles and temperature.
b.
the rate of diffusion increases with the increase in number of particles and temperature.
c.
the rate of diffusion increases with the increase in number of particles and decrease in temperature.
d.
the rate of diffusion decreases if the number of particles and temperature are kept constant.
e.
the rate of diffusion increases if the number of particles and temperature are kept constant.

B

Explanation:

Diffusion involves the movement of particles of a gas. They possess a kinetic energy which depends on the temperature of the gas. Increasing the temperature of the gas implies increasing the average kinetic energy of the molecules of the gas. If moregas molecules are present and their kinetic energy is increased by increasing the temperature, the rate of diffusion will definitely increase. Hence the answer.

distance, luminosity, brightness, radius, chemical composition, and temperature

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
