Why diffusion is faster in water?
This is because in hot water, the water molecules have more energy and are moving faster than the molecules of cold water. Because diffusion happens from high concentration to low concentration, the more molecules are moving, the more opportunities they have to mix together.
What is the slowest diffusing gas?
Chlorine is the slowest. We must assume that all these gases are at the same temperature.
Which diffuses faster air or oxygen?
Answer. Air diffuses faster than oxygen gas because the average density of air is less than the oxygen gas.
Which gas does not dissolve in water?
Nitrogen and methane gas are insoluble in water.
Which gas diffuses rapidly Why?
At any given temperature, small, light molecules (such as H 2, hydrogen gas) diffuse faster than larger, more massive molecules (such as N 2, nitrogen gas) because they are traveling faster, on the average (see heat ; kinetic-molecular theory of gases ).
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.
How many times faster is the rate of effusion of NH3 than CO2?
H will effuse 4.69 times faster than CO, 2. If the carbon dioxide in Problem 1 takes 32 sec to effuse, how long will the hydrogen take?
How many times the rate of diffusion of NH3 is greater than that of CO2?
Now, armed with the molecular weight of ammonia (17.03 g/mol) and the molecular weight of carbon monoxide (28.01 g/mol) we can determine how much faster ammonia effuses than carbon monoxide. So, ammonia diffuses approximately 1.28 times faster than carbon monoxide.
Which of the following has highest rate of diffusion?
NH3
What is the ratio of diffusion rate of oxygen to hydrogen?
1 : 4
Which gas is more ideal at STP?
Helium
Which gas is closest to ideal?
helium
What makes something an ideal gas?
An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly eleastic and in which there are no intermolecular attractive forces. In such a gas, all the internal energy is in the form of kinetic energy and any change in internal energy is accompanied by a change in temperature.
