Which of the following gases would have the greatest kinetic energy at 300 k?
a. n2
b. nh3
c. ar
d. all of them would have the same kinetic energy

D. All of them would have the same kinetic energy

Explanation:

The expression for the kinetic energy of the gas is:-

k is Boltzmann's constant =

T is the temperature

Since, kinetic energy depends only on the temperature. Thus, at same temperature, at 300 K, all the gases which are will posses same value of kinetic energy.

i think slash and

i think its 100

i hope this !
