At 350 C, nitrogen has a velocity of 800m/s. Find the velocity of hydrogen at the same temperature.

Answer : The velocity of hydrogen at the same temperature is, 2116.6 m/s

Explanation :

According to the Graham's law, the rate of effusion of gas is inversely proportional to the square root of the molar mass of gas.

In terms of velocity,

where,

= velocity of nitrogen = 800 m/s

= velocity of hydrogen = 800 m/s

= Molar mass of nitrogen = 14 g/mol

= Molar mass of hydrogen = 2 g/mol

Now put all the given values in the above expression, we get:

Therefore, the velocity of hydrogen at the same temperature is, 2116.6 m/s

it's c. elements are placed in rows based on how may valencies electrons have.

where are the choice options?
