Question

N2 (g) + 3H2 (g) -->2 NH3 (g)

The equation above is the equation for the Haber process.

If 2.0 moles of nitrogen are available for a reaction, what amount of hydrogen represents the correct stoichiometric ratio?

Answer 1

For each mole of nitrogen, you need 3 moles of hydrogen. Therefore, for two moles of nitrogen, six moles of hydrogen are needed.
