Question

28g of nitrogen is mixed with 12g of hydrogen to form ammonia as per the reaction N2+3H2=2NH3.which is the limiting reagent?​

Answer 1

Explanation:

We can see that, for 1 mole of N2 we require 3 moles of H2 to produce 2 moles of NH3 and here for 1 mole of N2 we have 6 moles of H2 i.e. we have 3 moles of excess H2 which will be unused. Thus for the given case N2 will be the limiting reagent.
