Uranium contains two isotopes, U-235 with an atomic mas of 235 g/mol, and u-238 with an atomic mass of 238g/mol. U-235 is needed

as a fuel in nuclear reactors. Until recently, the method used to separate U-235 from U-238 was by gas diffusion. Use U-235 as R1, and

U-238 as R2 and determine the rate of diffusion and which gas will diffuse faster.


⚪︎U-235 diffused 10.01 times faster than U-238

⚪︎U-235 diffused 1.01 times slower than U-238

⚪︎U-235 effused 2.01 times slower than U-238

⚪︎U-235 effused 1.01 times faster than U-238

⚪︎U-235 diffused 1.01 times faster than U-238

Final answer:

The rate of gas diffusion depends on its molecular weight. According to Graham's law, U-235 would diffuse 1.01 times faster than U-238 because of its slightly lower atomic mass.

Explanation:

This question deals with the concept of gaseous diffusion, a principle of physical chemistry. The rate of diffusion of a gas is inversely proportional to the square root of its molar mass according to Graham's law. Since U-235 has a slightly lower atomic mass than U-238, it would diffuse at a slightly faster rate. You can calculate the rate of diffusion using Graham's Law, which states that Rate1/Rate2 = √(M2/M1). If we assign U-235 as Rate1 and U-238 as Rate2 and plug in their atomic masses, the calculation would look like this: Rate of U-235 / Rate of U-238 = √(238/235). This gives us a result close to 1.01. Therefore, the correct answer is that U-235 diffused 1.01 times faster than U-238.
