Question:

The correction factor 'a' to the ideal gas equation corresponds to: electric field present between the gas molecules, forces of attraction between the gas molecules, density of the gas molecules, volume of the gas molecules

density of the gas molecules

volume of the gas molecules

forces of attraction between the gas molecules

electric field present between the gas molecules

Solution:

The correction factor 'a' to the ideal gas equation corresponds to forces of attraction between the gas molecules. Greater the value of 'a', more easily a gas can be liquefied. The unit of 'a' is atm L²mol⁻².
