In a traction `x+y + z_(2)to xyz_(2)`, Identity the limiting reagent If tiny, in the following traction mixtures.
(a) (A) 200 atoms of x+ 200 atoms of y+ 50 molecules of `z_(2)`
(b) 1 mol of x+1 mol of y +3 3 mol of`z_(2)`
(c) 50 atoms of x + 25 atoms of y + 50 molecules of `z_(2)`
(d) 2.5 mol of x + 5 mol of y + 5 mol of `z_(2)`

Explanation

`x+y +z_(2) to xyz_(2)`
(a)200 atoms of x+200 atoms of y+50 molecules of `z_(2)`
According to the traction. I atom of x tracts with one atom of y and one molecule of z to give product. In the case (a)200 atoms of x, 200 atoms of y react with 50 molecules of `z_(2)`. (1/4 part) t.e. 50 molecules of `z_(2)`, trad with 50 atoms of x and 50 atoms of y. Hence `z_(2)` is the limiting reagent.
(b) 1 mol of x + I mol of y + 3 mol of `z_(2)`
According to the equation 1 mole of `z_(2)`, only react with one mole of x and one mole of y . If 3 moles of `z_(2)` air their, x and y air the limiting reagents.
(c)50 atoms of x + 25 atoms of y + 50 molecules of `z_(2)`
, 25 atoms of y tract with 25 atoms of x and 25 molecules of `z_(2)`. So y is the limiting reagent.
(d) 2.5 mol of x + 5 mol of y + 5 mol of `z_(2)`
2.5 mol of x trad with 2.5 mole of y and 2.5 mole of `z_(2)`. So x is the limiting reagent.
