For the following reaction, find the value of q and predict the direction of change, given that a 1l flask initially contains 2 moles s8, 2 moles sf6, and 2 moles f2.
1/8 s8 (s) + 3 f2 (g) ⇄ sf6 (g) kc = 0.425
(a) q = k, system is at equilibrium
(b) q < k, reaction will make more reactants
(c) q < k, reaction will make more products
(d) q > k, reaction will make more reactants
(e) q > k, reaction will make more products

Consider the point on the plot where 10.0 g of naoh have been added. what amount of naoh, in moles, has been added? 0.308 mol fecl3 initially present
