Effusion refers to the process by which gas molecules escape through a small opening into a region of lower pressure. The rate of effusion is determined by the average speed of the gas molecules, which in turn depends on the molar mass of the gas. According to Graham's law of effusion, the rate of effusion of a gas is inversely proportional to the square root of its molar mass.
Given:
Left side: H2 gas at pressure p and temperature T
Right side: He gas at pressure 2p and temperature T
To determine the initial ratio of the rates of effusion, we need to compare the rates of effusion of H2 and He gases.
Let's assume the rate of effusion of H2 gas is r1 and the rate of effusion of He gas is r2.
According to Graham's law of effusion:
r1/r2 = sqrt(M2/M1)
where M1 and M2 are the molar masses of H2 and He gases, respectively.
The molar mass of H2 is 2 g/mol, and the molar mass of He is 4 g/mol.
Plugging these values into the equation, we get:
r1/r2 = sqrt(4/2) = sqrt(2)
Therefore, the initial ratio of the rates of effusion is sqrt(2).
To simplify the square root, we can approximate it as 1.41.
Therefore, the correct answer is option (c) 1.41.
This means that the rate of effusion of H2 gas is approximately 1.41 times faster than the rate of effusion of He gas.
