Ch 15 Flashcards
Examples of Equilibrium Processes
Vapor pressure above a solution
Concentration of gas dissolved in liquid
Amount of solute in a saturated solution
All apparent conversion has ceased
At chemical equilibrium
The forward and reverse reactions occur at the same rate
Keq < 1
Reactants
Keq > 1
Products

If a chemical reaction is endothermic what will happen to Kc with temp increase?
Increase
If a chemical reaction is exothermic what will happen to Kc with temp increase?
Decrease
At equilibrium, reactions can occur
In both forward and reverse directions
The magnitude of equilibrium constant allows one to predict
Whether products or reactants predominate at equilibrium
At equilibrium, concentrations
Remain constant
The equilibrium constant for a reaction is not affected by change in
Volume or pressure
