# Which gas travels faster and why in diffusion?

## Which gas travels faster and why in diffusion?

Gaseous particles tend to undergo diffusion because they have kinetic energy. Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy.

### Which two gases will diffuse at the same rate at the same temperature?

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 has highest rate of diffusion?

Ammonia has the highest rate of diffusion.

What does diffusion of gas depend?

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 diffusion active or passive?

There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.

## Why do gases diffuse at different rates?

Gaseous particles are in constant random motion. Gaseous particles tend to undergo diffusion because they have kinetic energy. Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy.

### Why diffusion in gases is faster than in liquids?

The molecules of gas have more kinetic energy than liquid molecules and are smaller. The distance between the constituent particles in gases becomes greater than in liquids, resulting in diffusion faster in gases than in liquids. Therefore, gas particles have higher kinetic energy and travel more rapidly.

#### What will happen if diffusion of gases are not taking place?

Answer: If diffusion doesn’t take place we can’t feel smell. This is one of the main problem than we are going to face.

In which case rate of diffusion is fastest?

Diffusion occurs in Solids, liquids and gases . Rate of diffusion in gases is high because they have large intermolecular space and they posses more kinetic energy than liquids and gases.

Which gas has slowest rate of diffusion?

As per Graham’s law, the rate of effusion or diffusion is inversely proportional to the square root of its molar mass. Hence, the gas with the highest molecular weight diffuses the slowest when it comes to rate of diffusion and helium is the fastest as it is the lightest.

## Can diffusion happen in liquids?

Diffusion in liquids Diffusion can also happen in liquids. This is because the particles in liquids can move around each other, which means that eventually they are evenly mixed. For example, potassium manganate(VII) is a purple solid.

### Does diffusion require ATP?

Simple diffusion does not require energy: facilitated diffusion requires a source of ATP. Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient.

#### What is meant by the diffusion of gases?

What is diffusion of gases in chemistry? Diffusion is the process whereby gaseous atoms and molecules are transferred from regions of relatively high concentration to regions of relatively low concentration. Effusion is a similar process in which gaseous species pass from a container to a vacuum through very small orifices.

Why is diffusion faster in gases than liquids?

Highly concentrated coffee molecules enter the cup of hot water.

• Coffee molecules begin to spread out in between the water molecules.
• Coffee molecules are now in a lower concentration than they started in.
• Why is the rate of diffusion highest in the gases?

Why is rate of diffusion very high in gases? Gaseous particles tend to undergo diffusion because they have kinetic energy. Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy. Graham’s Law states that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles.

## What are 10 types of gases?

• Acidic gases. These gases are chemically acidic in nature.
• Basic gases.
• Green House gases.
