Chromatogram results are considered to have better resolution if the RF values of the components being separated or further apart rather than closer together

False

Explanation:

False : It is better they are closer together

The RF ( retention factor  ) is calculated with this formula

= distance travelled / distance travelled by solvent

And the larger the RF factor of a compound the less polar the compound ( i.e. it will not stick to the stationary phase ) hence it is better the RF values of the components to be closer

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
