Which gas will have the lowest rate of diffusion?

Which gas will have the lowest rate of diffusion?


How does temperature affect the rate of diffusion?

When temperature increases, the kinetic energy of the particles has increased. The increased motion of the particles causes them to diffuse faster. Therefore, at higher temperatures, the rate at which fluid particles will diffuse is faster than at lower temperatures.

How does temperature affect the rate of diffusion in gases?

Temperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion. Solvent density: As the density of a solvent increases, the rate of diffusion decreases.

In which case rate of diffusion is highest?

Rate of diffusion is faster in gas because inter molecular attraction is comparatively less in gases.So they are very free to move as compared to solid materials.

Which will diffuse faster ammonia or CO2?

Which states that the rate of effusion of a gas is inversely proportional to its density. This means, the heavier the gas is(in terms of its molecular weight), the slower it is. Hence, ammonia is lighter and from Grahams law of effusion, it then means that it will diffuse faster than CO2, which is heavier.

Which of the gases diffuses faster among N O and CH Why?

Answer Expert Verified The lighter a gas is, the faster it will tend to diffuse. The molecular weight of CH4 is 16, of N2 28 and of O2 32 respectively. Therefore CH4 will diffuse fast, and then will N2, and eventually O2 will be seen diffusing.

How many times methane diffuses faster than SO2?

∴ Methane gas diffuses 2 times faster than SO2.

Which gas among co2 ch4 and h2 will diffuse faster and why?

The lighter the molecule, the faster will be the diffusion. In this case, Hydrogen has molecular mass of 2 while Carbon Dioxide has molecular mass of 44. So it is obvious that : Hydrogen will diffuse faster than Carbon Dioxide.

Does carbon dioxide diffuse faster than oxygen?

When gases are diffusing through liquids, for example across the alveolar membrane and into capillary blood, the solubility of the gases is important. The more soluble a gas is, the faster it will diffuse. Carbon dioxide is inherently more soluble than oxygen, and thus diffuses much faster than oxygen into liquid.

Does ethane diffuse faster than methane?

Which gas diffuses faster and why? A ethene Ethene molecules are heavier and so move faster. C methane Methane molecules are lighter and so move faster.

Why does neon gas diffuse faster than carbon dioxide?

Why does neon gas, Ne, diffuse faster than carbon dioxide gas, CO2 ?…

Effect of molecular mass Effect of temperature
C Lower molecular mass diffuses faster Diffusion is faster at higher temperature
D Lower molecular mass diffuses faster Diffusion is faster at lower temperature

Which gas diffuses faster hydrogen or helium?

Explanation: Graham’s law of diffusion states that the rate of diffusion is INVERSELY proportional to the square root of the molecular masses of each gas…. And thus dihydrogen will diffuse approx. 1.4 times faster than the more massive helium….

Why does ammonia gas diffuse faster than hydrogen chloride gas?

The ammonia gas, having a lower molecular weight than the hydrogen chloride, will diffuse faster and travel a greater length of the tube. Consequently, the white ring of ammonium chloride will form much closer to hydrochloric acid end of the tube.

Which two gases will diffuse at the same rate?

Therefore the rate of diffusion of different gases is inversely proportional to the square root of their mass densities. r = (1÷√d) Since CO2 and N2O only have the same molar mass, there mass density will be same. Therefore CO2 and N2O will diffuse with same rate.

Which gas is most easily liquefied?

Solution : NH3 can be liquefied easily as its molecules can interact through intermolecular hydrogen bonding which is possible because an H atom is directly bonded to a highly electronegative N atom with a lone pair.

Which gas would diffuse most rapidly under the same conditions of temperature and pressure?


What is the rate of diffusion?

The rate of diffusion, dn/dt, is the change in the number of diffusing molecules inside the cell over time. Since the net movement of diffusing molecules depends on the concentration gradient, the rate of diffusion is directly proportional to the concentration gradient (dC/dx) across the membrane.

What is the rate of diffusion dependent on?

The diffusion rate depends on several factors: the concentration gradient (the increase or decrease in concentration from one point to another); the amount of surface area available for diffusion; and the distance the gas particles must travel.

Is rate of diffusion directly proportional to pressure?

The rate of diffusion of a gas is inversely proportional to both time and square root of molecular mass. But it is directly proportional to pressure.
