Q. Which of the following represents total kinetic energy of one mole of gas?
A) $1/2\ RT$
B) $3/2\ RT$
C) $\left( C_{p} - C_{V} \right)\ RT$
D) $2/3\ RT$
Explanation
(b)
Total kinetic energy $= \frac{3}{2}nRT$
Where, $n =$ number of moles of gas
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ n = 1$
Then, $KE = \frac{3}{2}\ RT$
