Question

Under the same conditions of pressure and temperature, which property is the same for $H_2$ and $D_2$?

• A. rate of reaction with other substances
• B. average kinetic energy per mole
• C. most probable velocity
• D. maximum density

Answer 1

The correct option is B average kinetic energy per mole

Under the same conditions of pressure and temperature, average kinetic energy per mole is the same for $H_2$ and $D_2$.

Average kinetic energy per mole $=\frac{3}{2}RT$

Hence, option B is correct.
