JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
\(N _{2( g )}+3 H _{2( g )} \rightleftharpoons 2 NH _{3( g )}\) \(20 \;g \;\;\;\;5 \;g\) Consider the above reaction, the limiting reagent of the reaction and number of moles of \(NH _{3}\) formed respectively are
- A \(H _{2}, 1.42 \;moles\)
- B \(H _{2}, 0.71\; moles\)
- C \(N _{2}, 1.42\; moles\)
- D \(N _{2}, 0.71\; moles\)
Answer & Solution
Correct Answer
(C) \(N _{2}, 1.42\; moles\)
Step-by-step Solution
Detailed explanation
\(N _{2}( g )+3 H _{2}( g ) \rightleftharpoons 2 NH _{3}( g )\) \(W _{2}=20 g \quad 5 g\) \(n =\frac{20}{28} \quad \frac{5}{2}\) Stoichiometric Amount \(N _{2} \rightarrow \frac{20 / 28}{1}=\frac{20}{28} \quad H _{2} \rightarrow \frac{5 / 2}{3}=\frac{5}{6}\)…
