Question

what is the average kinetic energy of hydrogen molecule at NTP with full process​

Answer 1

Given:

A hydrogen molecule at NTP

To Find:

Average Kinetic energy of the hydrogen molecule

Solution:

KEavg = 3/2kT

where k is the Boltzman's constant and T  

= 273 + 20 K

= 293K

= 3/2 × 1.38 × 10-23 × 273

= 0.56 × 10`20J

Answer: The average kinetic energy of hydrogen molecule is 0.56 × 10`20J

Answer 2

KE = 0.56 * 10^-20 J

Explanation:

Formula to calculate th average kinetic energy of a hydrogen molecule = 3/2kT

Given NTP, so T is the absolute temperature = 273 K and k is the Boltzman's constant = 1.38 * 10^-23

Therefore KE = 3/2 * 1.38 * 10^-23 * 273

KE = 0.56 * 10^-20 J
