1. in the system shown below, there are 80 x particles, all in region a (the left half of the box). no extra particles can enter the system. when the system is in
equilibrium, what will be true of the particles?
a since there are no y particles, the system is already in equilibrium with ail 80 x particles in a
b. due to the constant motion of particles, this system will never reach equilibrium
c. in equilibrium, there will be exactly 40 x particles in a and 40 x particles in b, and those numbers will remain constant
din equilibrium, there will be approximately 40 x particles in a and 40 x particles in b, and those numbers will fluctuate but will remain near 40

the correct answer is d
