Answer: 3716.4 Joules
Explanation:
Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:
[tex]K=\frac{3nRT}{2}[/tex]
K= kinetic energy
n= number of moles = 1
R= gas constant = 8.314 J/Kmol
T= temperature in Kelvin =[tex]25^0C=(25+273)K=298K[/tex]
Putting in the values, we get
[tex]K=\frac{3\times 1\times 8.314\times 298}{2}=3716.4Joules[/tex]
Thus average kinetic energy of 1 mole of a gas at 25 degrees Celsius is 3716.4 Joules
