In class, there was an example with N2, H2, and NH3. Lavelle explained that taking away the product would increase product yield, but I'm not sure if I understand why.

Decreasing the amount of NH3 increases the yield of NH3 because the system would react in order to get back to chemical equilibrium. Taking away product in the system allows more reactants to react to form more product.

This is because the system would react in order to favor the production of NH3. Since you're removing NH3, it would allow the reactants to form more product

Decreasing the amount of NH3 would make Q<K, which would cause the reaction to shift right and more NH3 to form so that Q=K.

By taking away the product, the reaction is no longer in equilibrium, so more product will be produced to replace the amount taken away. It's more product yield in the sense that more product is being made, not necessarily more total product.

If you think of the reaction as a factory producing a product, an equilibrium for a factory is that the number of items built and broken down into parts again would leave the "equation" at a certain ratio. So when the factory gives away all its products or NH3 in the case of this equation. That leaves empty space where the foward reaction leads to resulting in more products or NH3.

When you take away some of the product, the reaction is no longer at equilibrium so it will continue reacting in the forward direction, yielding more NH3

The yield of NH3 Increases when the amount of NH3 decreases because if the yield didn't increase then system wouldn't be in chemical equilibrium, decreasing product leads to more reactions on the reactant side which lead to an increase in product.
