The ratio between kinetic energies of 16 g of

{O_2}

and 28 g of

{N_2}

respectively at 300 K will be

View answer and explanation

Correct option: B

0.043055556

Option B (0.043055556) is correct because the kinetic energy is directly proportional to the number of moles, and the ratio of moles of O2 to N2 multiplied by their respective molar masses gives the correct ratio.
