Verified step by step guidance1
Identify the balanced chemical equation given: \(\mathrm{N_2 + 3H_2 \rightarrow 2NH_3}\).
Look at the coefficients in front of each compound to determine the mole ratio. The coefficient in front of \(\mathrm{H_2}\) is 3, and the coefficient in front of \(\mathrm{NH_3}\) is 2.
Write the mole ratio of hydrogen gas to ammonia as the ratio of their coefficients: \$3 : 2$.
Interpret this ratio to mean that 3 moles of hydrogen gas react to produce 2 moles of ammonia.
Confirm that this ratio matches one of the answer choices, which is \$3 : 2$.
