What happens if Q is less than K?
If K > Q, a reaction will proceed forward, converting reactants into products. If K < Q, the reaction will proceed in the reverse direction, converting products into reactants.
What happens when Q K?
When Q=K, the system is at equilibrium and there is no shift to either the left or the right.
What is Delta G when Q K?
ΔG is related to Q by the equation ΔG=RTlnQK. If ΔG < 0, then K > Q, and the reaction must proceed to the right to reach equilibrium. If ΔG > 0, then K < Q, and the reaction must proceed to the left to reach equilibrium. If ΔG = 0, then K = Q, and the reaction is at equilibrium.
Is Q K spontaneous?
Recall that if Q < K, then the reaction proceeds spontaneously to the right as written, resulting in the net conversion of reactants to products. Conversely, if Q > K, then the reaction proceeds spontaneously to the left as written, resulting in the net conversion of products to reactants.
Does a precipitate form when Q K?
If Q = Ksp, a precipitate will form. If Q > Ksp, a precipitate will form. Note that precipitation may not happen immediately if Q is equal to or greater than Ksp.
What is K and Q in Chem?
It is important to understand the distinction between Q and K. Q is a quantity that changes as a reaction system approaches equilibrium. K is the numerical value of Q at the “end” of the reaction, when equilibrium is reached.
What is the relationship between Delta G and equilibrium constant K?
Both K and ΔG° can be used to predict the ratio of products to reactants at equilibrium for a given reaction. ΔG° is related to K by the equation ΔG°=−RTlnK. If ΔG° < 0, then K > 1, and products are favored over reactants at equilibrium. If ΔG° > 0, then K < 1, and reactants are favored over products at equilibrium.
How do you predict the formation of a precipitate?
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.
What is r in Delta G LNK?
R = 8.314 J mol-1 K-1 or 0.008314 kJ mol-1 K-1. T is the temperature on the Kelvin scale.
