Gases with high molecular weights diffuse more slowly than gases with lower molecular weights.
2 answers:
Answer:
The given statement is true.
Explanation:
Graham's Law:
This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molecular mass of the gas. The equation given by this law follows the equation:
- Higher the molecular mass lower will be effusion rate.
- Lower the molecular mass higher will be the effusion rate.

In chemistry, the idea of combining atomic orbitals to create new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) is known as orbital hybridisation (or hybridization). These new hybrid orbitals are suitable for the pairing of electrons to form chemical bonds in valence bond theory.
Because more directional hybridised orbitals result in higher overlap when creating bonds, stronger bonds are formed, which favours the hybridization of orbitals. When hybridization takes place, this leads to more stable molecules.
One s orbital and three p orbitals combine to form four orbitals, each of which has a 25% s character and a 75% p character. This process is known as
hybridization. Anytime an atom is surrounded by four groups of electrons, this kind of hybridization is necessary.
