<u>Answer:</u> The order of reactivity will be F > O > N > C > B.
<u>Explanation:</u>
Reactivity of an element is defined as the tendency for it to gain or loose electrons easily.
From the given elements, all are non-metals except boron.
Boron is a metalloid and it does not attract or loose electrons easily. Hence, it is the least reactive element.
Reactivity of non-metals increases across a period because of the decrease in size and electrons are more attracted towards the nucleus and hence, can gain electrons easily. Therefore, the most reactive metal will be fluorine.
Hence, the order of reactivity will be F > O > N > C > B.
K = 0.058 yr (constant)
Fraction of the pesticide = 36 years/12 = 3 half-lives , so around 1/8 left
when 99.9 % decomposed, 0.1 % is left , so the fraction is 0.001. To reach this point, it will take around +/- 120 years
