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:
\(K=\frac{3nRT}{2}\)
K= kinetic energy
n= number of moles = 1
R= gas constant = 8.314 J/Kmol
T= temperature in Kelvin =\(25^0C=(25+273)K=298K\)
Putting in the values, we get
\(K=\frac{3\times 1\times 8.314\times 298}{2}=3716.4Joules\)
Thus average kinetic energy of 1 mole of a gas at 25 degrees Celsius is 3716.4 Joules
