Question

when 2 mole of NH3 is allowed to react with 3 mole of 02 then​

Answer 1

Answer:

0.8mole .............. answer

Answer 2

from balanced chemical eq.

4 moles of NH3 reacts with 5 moles of O2

therefore, 1 mole of NH3 react with 1.25 moles of O2

and 2 mole of NH3 react with 2.50 moles of O2

but given is 3 mole of O2

hence NH3 is limiting reagent and O2 is excess reagent
