  • To aid students in visualizing an increase in entropy, many elementary chemistry texts use artists' before-and-after drawings of groups of "orderly" molecules that become "disorderly". This seems to be a useful visual support, but it can be so misleading as actually to be a failure-prone crutch. Ten examples illustrate the problem.Entropy is not disorder, not a measure of chaos, not a driving force. Energy's diffusion or dispersal to more microstates is the driving force in chemistry. Entropy… CONTINUE READING
