What is the temperaure at which the kinetic energy of 0.3 mole of helium is equal tp the kinetic energy of 0.4 mole of argon at 400K

A

400K

B

873 K

C

533K

D

300K

Text Solution

Verified by Experts

(c ) We know that, the kinetic energy=Nrt
Kinetic energy of helium =0.3xxRxxT …(I)
Kinetic energy of argon=0.3xxRxx400…(ii)
According to question
Kinetic energy of helium=kinetic energy of argon
`0.3xxRxxT=0.4xxRxx400`
T=533K
