Solution


Q.

The total kinetic energy of 1 mole oxygen at 27°C is :

[Use universal gas constant (R) = 8.31J/ mole K]                [2024]
1 6845.5 J  
2 5942.0 J  
3 6232.5 J  
4 5670.5 J  

Ans.

(3)   

            Kinetic energy = f2nR

                                    =52×1×8.31×300J=6232.5J
