nitrogen gas and hydrogen gas react to produce ammonia according to the following equation.
$n_{2}+3h_{2}\to 2nh_{3}$
which ratio of components is correct?
(1 point)
for every mole of nitrogen gas, the reaction produces 1 mole of ammonia
for every 2 moles of nitrogen gas, the reaction requires 3 moles of hydrogen gas.
for every 3 moles of hydrogen gas, the reaction produces 2 moles of ammonia.
for every mole of hydrogen gas, the reaction produces 2 moles of ammonia.

Explanation:

Step1: Analyze the reaction equation

The balanced chemical equation is \(N_{2}+3H_{2}\to2NH_{3}\). This means that for every 1 mole of \(N_{2}\), 3 moles of \(H_{2}\) react to produce 2 moles of \(NH_{3}\).

Step2: Check each option

• Option 1: For every mole of \(N_{2}\), 2 moles of \(NH_{3}\) are produced (not 1), so this is incorrect.
• Option 2: For every 1 mole of \(N_{2}\), 2 moles of \(NH_{3}\) are produced. So for 2 moles of \(N_{2}\), 4 moles of \(NH_{3}\) are produced (not related as per the option), so this is incorrect.
• Option 3: For every 1 mole of \(N_{2}\), 3 moles of \(H_{2}\) are required. So for 2 moles of \(N_{2}\), 6 moles of \(H_{2}\) are required (not as per the option), so this is incorrect.
• Option 4: From the equation \(3H_{2}\to2NH_{3}\), for every 3 moles of \(H_{2}\), 2 moles of \(NH_{3}\) are produced. This is correct.

Answer:

For every 3 moles of hydrogen gas, the reaction produces 2 moles of ammonia.
