WebNov 16, 2016 · When this is the case and all values are given in pressures, we use K p, which is the equilibrium constant for pressure. So K c for Concentration and K p for Pressure. You use Q when you are unsure if a reaction is at equilibrium. Say for example you are in a lab and don't know how long a reaction takes. WebMar 25, 2024 · Each reaction has three different conditions: Q > K, Q = K, and Q < K. The quiz rotates through them. The quiz is not randomized. All students will see the 15 sets of …

WebTranscript We can use the reaction quotient to predict whether a precipitate will form when two solutions containing dissolved ionic compounds are mixed. If Q < Kₛₚ, the newly mixed solution is undersaturated and no precipitate will form. If Q > Kₛₚ, the solution is oversaturated and a precipitate will form until Q = Kₛₚ. Created by Jay.
