Achemical reaction a ! b is carried out in a closed vessel. the following data are taken for the concentration of a, ca g/l, as a function of time, t min, from the start of the reaction: ca0 ca0 cae cae ca (g/liter) ca(g/liter) t(min) t(min) 0.1823 0.1453 0.1216 0.1025 0.0795 0.0495 0 36 65 100 160 [infinity] a proposed reaction mechanism predicts that ca and t should be related by the expression ln ca cae ca0 cae kt where k is the reaction rate constant. (a) do the data support this prediction? if so, plot the data appropriately to determine the value of k. (b) if the tank volume is 125 l and there is no b in the tank at t 0, how much b(g) does the tank contain after two hours? (c) estimate the time required for the final concentration of a to reach 1.1, 1.05, and 1.01 times cae, and determine the mass of b produced at each of these conditions for the reactor described in part (b).

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
