increasing yield of NH3

Postby ursulavictorino1K » Sun Jan 12, 2020 6:51 pm

Why is it that in order to increase the yield of NH3, you could remove NH3? Wouldn't that just decrease the amount of NH3?

To increase yield of NH3, you would need to increase the amount of reactants

Removing some of the NH3 makes the reaction form more products to reach equilibrium, so more NH3 would be produced

By removing NH3 from the system, the numerator of the Qp equation will decrease, resulting in a smaller Qp value. When Qp is less than Kp the reaction moves forward, resulting in more NH3 being created.

Yes it would decrease NH3 in the system, but overall you would have more NH3 (by adding NH3 in the system plus the amount removed and stored separately from the system)
