Calculate the total and average kinetic ...

Calculate the total and average kinetic energy of `32 g` methane molecules at `27^(@)C (R =8.314 JK^(-1) mol^(-1))` .

Text Solution

Verified by Experts

Total kintic energy ` =(3)/(2) nRT`
`= (3)/(2) xx (32)/(16) xx 8.314 xx 300 =7482.6 J`
Average kietic energy `= (3)/(2) (RT)/(N)`
`(3)/(2) xx (8.314 xx 300)/(6.023 xx 10^(23)) = 6.21 xx 10^(-21) J` .
