Recall that when a reaction is at equilibrium, the forward and reverse reactions occur at the same rate.
To illustrate this idea, consider the reaction of A (small, red spheres) and B (large, blue spheres) to form AB.
A+B=AB
The image shows a snapshot of the reaction at equilibrium.
Although the image only shows a snapshot of the reaction at equilibrium, the reaction never stops. Even after several minutes,
there is some A and B left unreacted, and the forward and reverse reactions continue to occur. Also, the amounts of each species
(i.c., their concentrations) stay the same.
Assume each atom or molecule represents a 1 M concentration of that substance. What is the value of the equilibrium constant
for this reaction?
