What is the limiting reagent when 1.5 moles of nitrogen react with 6 moles of hydrogen? N2(g)+3H2(g)—> 2NH3(g)

Explanation

Given

N2(g)+3H2(g)—> 2NH3(g)

Number of moles of nitrogen = 1.5 moles

Number of moles of hydrogen = 6 moles

Required: Limiting reagent

Solution

For Nitrogen:

For Hydrogen:

The limiting reagent is Nitrogen, because less moles of NH3 will be produced by nitrogen, meaning it all of it gets used up.

Answer

The limiting reagent is Nitrogen.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
