Question

At STP, 0.50 mol gas and 1.0 mol He gas.

A

Have equal average kinetic energies

B

Have equal molecular speeds

C

Occupy equal volumes

D

Have equal effusion rates

Answer

Have equal average kinetic energies

Explanation

Solution

For same temperature kinetic energies of $\mathrm { H } _ { 2 } \& \mathrm { He }$ molecules will be same because kinetic energy depends only on temperature.
