At STP, 0.50 mole `H_(2)` gas and 1.0 mole He gas

A

Have equal average kinetic energies

B

Have equal molecular speeds

C

Occupy equal volumes

D

Have equal effusion rates

Text Solution

Verified by Experts

The correct Answer is:
A
For same temperature kinetic energies of `H_(2)` & He molecule will be same because kinetic energy depends only on temperature.
