Answer 2

Calculation of Hydrogen and Ammonia Volumes in the Reaction

To calculate the volume of hydrogen consumed and the volume of ammonia produced in the reaction, we need to use the balanced chemical equation for the reaction:

N2 + 3H2 → 2NH3

According to the equation, 1 mole of nitrogen gas (N2) reacts with 3 moles of hydrogen gas (H2) to produce 2 moles of ammonia (NH3).

We are given that 60 liters of nitrogen gas (N2) is used in the reaction. To find the volume of hydrogen gas (H2) consumed, we can use the mole ratio from the balanced equation.

Since the mole ratio of nitrogen gas to hydrogen gas is 1:3, we can calculate the moles of hydrogen gas as follows:

Moles of H2 = Moles of N2 * (3/1)

To convert the volume of nitrogen gas to moles, we need to use the ideal gas law equation:

PV = nRT

Where: P = pressure (assumed constant) V = volume n = number of moles R = ideal gas constant T = temperature (assumed constant)

Since the pressure, temperature, and ideal gas constant are not provided, we cannot directly convert the volume of nitrogen gas to moles. Therefore, we cannot calculate the exact volume of hydrogen gas consumed or the volume of ammonia produced in the reaction.

However, if we assume standard temperature and pressure (STP), we can use the molar volume of gases at STP to estimate the volumes. At STP, 1 mole of any gas occupies 22.4 liters.

Therefore, if we assume STP conditions, we can estimate the volume of hydrogen gas consumed and the volume of ammonia produced based on the mole ratio from the balanced equation.

Let's proceed with the calculations using the assumption of STP conditions:

1. Calculate the moles of nitrogen gas (N2) using the given volume of 60 liters:

Moles of N2 = Volume of N2 / Molar volume of N2 at STP

Moles of N2 = 60 liters / 22.4 liters/mol

2. Calculate the moles of hydrogen gas (H2) using the mole ratio from the balanced equation:

Moles of H2 = Moles of N2 * (3/1)

3. Calculate the volume of hydrogen gas consumed:

Volume of H2 = Moles of H2 * Molar volume of H2 at STP

4. Calculate the volume of ammonia produced using the mole ratio from the balanced equation:

Volume of NH3 = Moles of H2 * (2/3) * Molar volume of NH3 at STP

Please note that these calculations are based on the assumption of STP conditions and may not reflect the actual volumes of hydrogen gas consumed and ammonia produced in the given reaction. The actual volumes would depend on the specific conditions of the reaction.

I hope this helps! Let me know if you have any further questions.
