For a gas sample containing equimolar amounts of carbon monoxideand heliumat 300 K, heliumhas average speed and average kinetic energy compared tocarbon monoxidegas. a.a lower; the same b. the same; the same c. a higher; the same d. a higher; higher

Option C (a higher; the same) is the appropriate response.

Explanation:

Given:

Temperature,

T = 300 K (both and )

As we know,

Average speed of a molecule,

⇒

Thus, the average speed of will be lower as its molar mass is greater than .

Now,

⇒ (not depend on molar mass)

Hence, it will be the same.

The other three alternatives aren't connected to the scenario given. So the above is the correct answer.

your answer would be “dry”
