Answer:
Argon
Explanation:
The average kinetic energy of the particles in a gas is given by

where
m is the mass of the particles
v is their rms speed
The average kinetic energy of the particles in a gas can also be written as

where
k is the Boltzmann's constant
T is the absolute temperature of the gas
Combining the two equations,

We can re-write the equation as

We see that:
- The speed is directly proportional to the square root of the temperature
- The speed is inversely proportional to the square root of the mass of the particles
Therefore, if the two gases are at same temperature, the particles will move faster in the gas with lighter particles (smaller mass).
Since Krypton atoms have larger mass than Argon atoms, it means that atoms in Argon move faster than in Krypton.
