A+ m ↔ a* + m (k1; k2) a* → b +c (k3) a) derive a rate expression for this reaction in terms of ca and cm. state any simplifying assumptions. b) under what conditions would the reaction exhibit first-order behavior, second-order behavior? c) assume this reaction can be approximated as a pseudo-first order reaction, determine the retention time required for a 70% completion in a batch, cstr, and pfr reactor, respectively. (for this part, use k1 = 0.001 s-1, k2 = 0.02 s-1, and k3 = 0.001 s-1.)

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
