Question
According to Le Chatelier's principle, what happens to the equilibrium of the reaction if more phosphorus (P) is added to the equilibrium mixture of each of the following reactions?
2PH3(g) 3H2(g) + 2P(g)
2P(g) + O2(g) 2PO(g)
2PO2(g) 2P(s) + 2O2(g)
2P(s) + 3Cl2(g) 2PCl3(g)
This reaction has phosphorus as a reactant. Adding a reactant shift the equilibrium to the reactant (RSL).
This reaction has phosphorus as a product. Adding a product shift the equilibrium to the product (RSR).
This reaction has phosphorus as a reactant. Adding a reactant does not cause a shift in the equilibrium (NC).
This reaction has phosphorus as a reactant and product. Adding both reactant and product does nothing to the equilibrium (NC).
Not enough information to determine the shift.
This reaction has phosphorus as a product. Adding a product shifts equilibrium to reactants (RSL).
This reaction has phosphorus as a product. Adding a product does not cause a shift in the equilibrium (NC).

Explanation / Answer
2PH3(g) 3H2(g) + 2P(g)
f.This reaction has phosphorus as a product. Adding a product shifts equilibrium to reactants (RSL).
2P(g) + O2(g) 2PO(g)
h.This reaction has phosphorus as a reactant. Adding a reactant shifts equilibrium to products (RSR).
2PO2(g) 2P(s) + 2O2(g)
g.This reaction has phosphorus as a product. Adding a product does not cause a shift in the equilibrium (NC).
2P(s) + 3Cl2(g) 2PCl3(g)
c.This reaction has phosphorus as a reactant. Adding a reactant does not cause a shift in the equilibrium (NC).
