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.
