What is the temperature at which the kinetic energy of 0.3 moles of helium is equal to the kinetic energy of 0.4 moles of argon at 400 K. ?

A

400 K

B

873 K

C

533 K

D

300 K

Text Solution

Verified by Experts

The correct Answer is:
c
KE = nRT
Kinetic energy of helium = Kinetic energy of argon
`0.3 xx R xx T = 0.4 xx R xx 400`
T = 533K
