Consider the following system of gas-phase reactions: B is the desired product, and X and Y are foul pollutants that are expensive to get rid of. The specific reaction rates are at 27 C. The reaction system is to be operated at 27 C and 4 atm. Pure A enters the system at a volumetric flow rate of 10 dm 3 /min. (a) Sketch the instantaneous selectivities as a function of the concentration of C A . (b) Consider a series of reactors. What should be the volume of the first reactor

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.
