The average kinetic energy of an ideal gas per molecule in SI unit at 25^ C will be

Options

  1. A6.17 10⁻²¹ ~kJ
  2. B6.17 10⁻²¹ ~J
  3. C6.17 10⁻²⁰ ~J
  4. D7.16 10⁻²⁰ ~J

Correct answer

B. 6.17 10⁻²¹ ~J

Step-by-step solution

KE = 3 2 kT = 3 2 8.313 6.023 10²³ 298=6.17 10⁻²¹ ~J (Average Kinetic energy . KE = 3 2 k T = 3 2 R N T )
