Kinetic Theory Of Gases Question 55
Question: The average translational kinetic energy of $ O _{2} $ (relative molar mass 32) molecules at a particular temperature is 0.048 eV. The translational kinetic energy of $ N _{2} $ (relative molar mass 28) molecules in eV at the same temperature is
Options:
A) 0.0015
B) 0.003
C) 0.048
D) 0.768
Show Answer
Answer:
Correct Answer: C
Solution:
[c] Average translational kinetic energy of an ideal gas molecule is $ \frac{3}{2}kT $ which depends on temperature only
Therefore, if temperature is same, translational kinetic energy of $ O _{2} $ and $ N _{2} $ both will be equal.
