Explanation:

The average kinetic energy of a hydrogen gas molecule at NTP will be (Boltzmann's constant k = 138 x 10-23 J/K) 0.186 × 10-20 J. 0.372 × 10-20 J.

The kinetic energy per molecule of hydrogen gas at NTP is 6.06 × 10^-21 J/molecules.

Given: A molecule of hydrogen gas at NTP

To Find: the kinetic energy per molecule of hydrogen gas at NTP

Solution:

  • We know that NTP stands for Normal Pressure and Temperature.
  • The value of temperature at NTP and the value of pressure at NTP is 1 atm.
  • The kinetic energy per molecule of Hydrogen gas can be calculated using the formula,  

        K.E = 3/2 × kT      

where, k = Boltsman's constant = 1.38 × 10^-23 , T = 293 K

Using the formula, we can solve;

        K.E = ( 3/2 × 1.38 × 10^-23 × 293 ) J/molecules

                = 6.06 × 10^-21 J/molecules

Hence,

The kinetic energy per molecule of hydrogen gas at NTP is 6.06 × 10^-21 J/molecules.
