Consider the subsequent generic equilibrium in which a solid reactant is in equilibrium with a gaseous product. The subsequent diagrams represent the reaction mix at the following points (a) initially; (b) after a short period of time has passed as well as (c) at equilibrium. For each diagram compute the concentrations of the spheres representing A(s) and B(g). Presume that each block in the grid has an area of and report your answer in units of since the spheres in the solid aren't free to move, the solid only occupies the area that it covers. The spheres in the solid, however, are free to move as well as therefore occupy the entire grid.) Explain what do you notice about the concentrations of A(s) and B(g) in these representations? State an equilibrium expression for the generic reaction as well as use the results of your Compute to explain why A(s) isn't included in the expression. spheres>cm2.1 cm2 A(s)?B(g)
