Experiment: Click Reset. Set the Wall to 50%, x in A to 100, y in B to 0, Temp. to 100 K,
and Particle mass to 15 amu (atomic mass units). Select the TABLE tab. Press Play.
Click Pause when x in A first reaches 55% or below. Record this Time to reach
equilibrium in the left table below.
Repeat four more times at 100 K, and then run five trials with the temperature set to 600 K.

4. Calculate: Find the average time to reach equilibrium for each experiment:
A. Average time to reach equilibrium at 100 K:
B. Average time to reach equilibrium at 600 K:
5. Draw conclusions: Compare the average times to reach equilibrium for each temperature.
A. How did temperature affect the rate of diffusion?
