Question

The average kinetic energy of uf6(g) is 4.98 kj/mol at some temperature. what is the average kinetic energy of sf6(g) at that same temperature?

Answer 1

4.98 kJ/mol would be the answer I believe :) hope this helped

Answer 2

The average kinetic energy of SF₆(g) is 4.98 kj/mol.

Step-by-step explanation:

Given that,

Kinetic energy of UF₆(g)=4.98\ kj/mol

We need to calculate the average kinetic energy of SF₆(g)

Using formula of average kinetic energy

`E_(avg)=(3)/(2)kT`

`E_(avg)=(3)/(2)(RT)/(N_(A))`

Where, k = Boltzmann constant

`N_(A)` =Avogadro number

R =gas constant

Here, average kinetic energy depends only on temperature not on special molar mass

So, The SF₆(g) average kinetic energy is same as UF₆(g

Hence, The average kinetic energy of SF₆(g) is 4.98 kj/mol.
