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

Answer»

`"56 G of "N_(2)+"10 g of "H_(2)`
`"35 g of "N_(2)+"8 g of "H_(2)`
`"28 g of "N_(2)+"6 g of "H_(2)`
`"14 g of "N_(2)+"4 g of "H_(2)`

Solution :According to the stoichiometry of balanced equation `28g N_(2)` react with `6gH_(2)`
`underset("28g")underset("1 mole")(N_(2))+underset("6g")underset("3 mole")(3H_(2))RARR 2NH_(3)`
`therefore"For 56 g of "N_(2), 12 g " of " H_(2)` is required.
