For a reaction, `N_(2)(g)+3H_(2)(g)rarr2NH_(3)(g)`, identify dihydrogen `(H_(2))` as a limiting reagent in the following reaction mixtures.

Options

A. 14 g of `N_(2)` + 4 g of `H_(2)`
B. 28 g of `N_(2)` + 6g of `H_(2)`
C. 56 g of `N_(2)` + 10 g of `H_(2)`
D. 35 g of `N_(2)` + 8 g of `H_(2)`

Answer

C

Explanation

`N_(2) (g) + 3H_(2)(g) to 2NH_(3)(g)`
(a) 0.5 mol 2 mol (limiting reagent)
(b) 1 mol , 3 mol (completion of reaction)
( c) 2 mol , 5 mol
( d) 1.25 mol, 4 mol (limiting reagent)
