What is average kinetic energy?

What is the average kinetic energy of a gas at 285 Kelvin? (R = 8.314 J/K-mol)?

  • What is the average kinetic energy of a gas at 285 Kelvin? (R = 8.314 J/K-mol) 2.37 x 103 J/mol 7.11 x 103 J/mol 3.55 x 103 J/mol 1.77 x 103 J/mol

  • Answer:

    KE = (3/2)RT KE = (1.5)(8.314 J/molK)(285K) = 3.55X10^3 J/mol
