2COF2(g) = CO2(g) + CF4(g) Keq = 53.6
0.5 mol of COF2, 3.6 mol of CO2, and 4.00 mol of CF4 is added to a 10L flask.?

a) Will the reaction move to left or right to establish equilibirium. Show your work please. Hint: Q= 57.6
b) Will CoF2 increase or decrease? Why?
c) Will total pressure change ? Why?

2. PCL5 (g) = PCl3(g) + Cl2(g) Keq = 33.3
8 mol of PCl5, 6 mol of PCl3, and 4 mol of Cl2 is added to a 2L flask.

a) Will the reaction move to left or right. Show work to support your answer. Hint: Q=1.5
b) Will PCl5 increase or decrease? Why?
c) Will pressure increase or decrease. Why?

Show your work please.

Probably best part of your post.

I know that left or right has something to do with Keq, but I am not sure what the relation is.

Welcome to the forum.  Please read the forum rules.  We can only help you after you have shown us your attempt or thoughts.  I will give you a small hint.  There is a difference between an equilibrium constant and equilibrium.

Yeah, I went over and read the entire chapter and found that right or left depends on Q and Keq and so does increase in pressure and concentration,

Well, then goes ten minutes of my time reading an entire chapter.

Yeah, I went over and read the entire chapter and found that right or left depends on Q and Keq and so does increase in pressure and concentration,

"Left or right" really need proper definitions.  If I say that the equilibrium shifts to the right, it means that more product has formed.

The final concentrations of reactants and products does indeed depend on both Q and K_eq, but my original point was a little different.  Does the value of Q change with changes in concentration of the reactants or products?  Does the value of K_eq change with changes in the concentration of reactants or products?
