Lconsider the following reaction: ch3br(aq)+oh−(aq)−→−ch3oh(aq)+br−(a q) the rate law for this reaction is first order in ch3br and first order in oh−. when [ch3br] is 5.0×10−3m and [oh−] is 0.050 m, the reaction rate at 298 k is 0.0432m/s. (a) what is the value of the rate constant? (b) what are the units of the rate constant? (c) what would happen to the rate if the concentration of oh− were tripled? (d) what would happen to the rate if the concentration of both reactants were tripled?

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.
