Question

A chemical equilibrium between gaseous reactants and products is shown.

N2(g) + 3H2(g) ⇌ 2NH3(g)

How will the reaction be affected if the pressure on the system is increased?

It will shift toward the reactant side as there is lower pressure on the reactant side.
It will shift toward the product side as there is higher pressure on the product side.
It will shift toward the reactant side as there are a greater number of moles of gas on the reactant side.
It will shift toward the product side as there are a fewer number of moles of gas on the product side.

Answer 1

When the pressure is increased, the reaction shifts to favor the side w/ fewer moles of gas

so looking at your reaction, which side has fewer moles of gas? Products or reactants?

Answer 2

Its D.) right " It will shift toward the product side as there are a fewer number of moles of gas on the product side."

Answer 3

good, product side has 2 moles per the reactant's sides 4 moles. that's correct.
