Which gas has the greatest kinetic energy at STP O CH3Cl CH4

Which gas has the greatest kinetic energy at STP? O CH3Cl CH4 O none of the above (all have the same kinetic energy)

kinetic energy of gaseous paritcles are given as K.E. = (3/2)* K * T

where K is Boltazman\'s Constant and T is temperature.

so Kinetic energy of gaseous molecule deands only on temperature. and if temperature is same than kinetic energy is same for all molecules.

here Conditions is STP mean temperature is constant. so kinectic energy is same for all three molecule (CH₃Cl, CCl₄ and CH₄)

so answer is option 4th

None of the above(all have same kinetic energy).
