11. The K'eq of the reaction A ⟺ B = 0.25. If we instantaneously set the concentration of substrate A at 4M and the concentration of product B at 1M, what would happen?
A) The reaction would proceed in reverse, with B being converted to A until equilibrium was reached.
B) The reaction would proceed forward, with A being converted to B until equilibrium was reached.
C) The reaction would not proceed in either direction because it was already at equilibrium.
D) More information is needed to determine whether the reaction would proceed.

Question 1 In the reaction: CO2(g) + C(s) --> 2CO(g), how might the concentration of C(s) (graphite) affect the equilibrium concentration of the product CO(g)? a. It does not affect it at all because C(s) is not included in the expression of the equilibrium constant. Thus, whether C(s) is present or not does not affect the reaction. b. It doesn't affect it as long as there is C(s) present during the reaction (i.e. C(s) is in excess so it does...
