6) A 0.160 mol sample of PCls(g) is put in a rigid 1.0 L container at an unknown temperature. After a period of time, the system comes to equilibrium. A graph
showing the concentration of PCls(g) as a function of time has been plotted
below.
PCls(g) = PC13(g) + Cl2(g)

a. What was the concentration of PCls when the system established
equilibrium?
b. Find the concentrations of PCl3 and Cl2 at equilibrium. (Hint: Use an ICE
chart with the initial and equilibrium concentrations of PCI).
c. On the above graph, sketch curves that show how the concentrations of
PClz and Cl, change over time.
d. Calculate the value of the equilibrium constant K for the reaction at this
temperature.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
