Question

n₂ + 3h₂ --> 2nh₃
how many moles of hydrogen are needed to react with 2 moles of nitrogen?

Explanation:

Step1: Analyze the reaction ratio

From the balanced equation \(N_2 + 3H_2
ightarrow2NH_3\), the ratio of \(N_2\) to \(H_2\) is \(1:3\).

Step2: Calculate the moles of \(H_2\)

If there are \(n(N_2) = 2\) moles, and using the ratio \(\frac{n(N_2)}{n(H_2)}=\frac{1}{3}\), then \(n(H_2)=3\times n(N_2)\). Substituting \(n(N_2) = 2\) moles, we get \(n(H_2)=3\times2 = 6\) moles.
