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...
