In the ammonia synthesis reaction, 30 liters of hydrogen reacted. calculate the volume of nitrogen reacted.

Given:
V (H2) = 30 l

To find:
V (N2) -?

Decision:
1) Write the equation of a chemical reaction:
3H2 + N2 => 2NH3;
2) Calculate the amount of substance H2 (under normal conditions):
n (H2) = V (H2) / Vm = 30 / 22.4 = 1.34 mol;
3) Determine the amount of substance N2 (taking into account the coefficients in the reaction equation):
n (N2) = n (H2) / 3 = 1.34 / 3 = 0.45 mol;
4) Calculate the volume N2:
V (N2) = n (N2) * Vm = 0.45 * 22.4 = 10.08 liters.

Answer: The volume of N2 is 10.08 liters.
