At what temperature will the total kinetic energy of 0.30 mol of helium be same as the total kinetic energy of 0.40 mol of argon at 500 K.

A

400 K

B

300 K

C

533 K

D

573 K

Text Solution

Verified by Experts

The correct Answer is:
C
`K.E.=(3)/(2)nRT`
`:. (3)/(2)xx.04xx400=(3)/(2)xx0.3xxT" or "T=533" K"`
