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

Options

  1. A6.17 10⁻²¹ J
  2. B6.17 10⁻²¹ kJ
  3. C6.17 10²⁰ J
  4. D7.16 10⁻²⁰ J

Correct answer

A. 6.17 10⁻²¹ J

Step-by-step solution

Average kinetic energy per molecule = 3 2 K T aligned & = 3 2 1.38 10⁻²³ 298 & =6.17 10⁻²¹ J per molecule aligned
