a. The atomic radii is the same for both argon and the unknown gas.

atomic radii is unique for each atom

b. The effusion rate is the same for both argon and the unknown gas.

different molar mass → different effusion rate

c. The number of moles is the same for both argon and the unknown gas.

number of moles can be equal

d. The temperature is the same for both argon and the unknown gas.

temperature can be equal
