Question

3 moles of n2 combines with 5 moles of h2 to form nh3 by haber's process. 1) which is limiting reagent?

Answer 1

3 moles of n2 combines with 5 moles of h2 to form nh3 by haber's process. whe have to identify limiting reagent.

chemical reaction of Nitrogen and hydrogen is shown by ....

$N_2+3H_2\rightarrow 2NH_3$

here it is clear that 1 mole of nitrogen reacts with 3 moles of hydrogen.

so, 3 mole of nitrogen reacts 9 mole of hydrogen.

but here given only 5 moles of hydrogen.

hence, hydrogen is not given in sufficient amount. so, hydrogen is limiting reagent.
