Chapter 14 Flashcards
Dynamic equilibrium
Forward reaction rate has decreased, reverse reaction rate has increased. Forward and reverse reactions are happening at an equal rate. Product and reactant concentration are not equal
Forward reaction rate has decreased, reverse reaction rate has increased. Forward and reverse reactions are happening at an equal rate. Product and reactant concentration are not equal
Dynamic equilibrium
Equilibrium constant (k)
Numerical constant of an equilibrium constant expression at a particular temperature
Numerical constant of an equilibrium constant expression at a particular temperature
Equilibrium constant (k)
Equilibrium constant expression
Ratio of concentrations or pressures of products to reactants. Each term to the power of its stoichiometric coefficient
Ratio of concentrations or pressures of products to reactants. Each term to the power of its stoichiometric coefficient
Equilibrium constant expression
k(eq)»_space;1 (large)
Reaction favours product side. Equilibrium is shifted to the right
Reaction favours product side. Equilibrium is shifted to the right
k(eq)»_space;1
k(eq) «1
Reaction favours reactants. Equilibrium shifts to the left
Reaction favours reactants. Equilibrium shifts to the left
k(eq) «1
k(eq) =1
Neither side of the reaction is favoured. Products and reactants are equal
Neither side of the reaction is favoured. Products and reactants are equal
k(eq) =1
k(p) = k(c)
Only when mols of gas doesn’t change during a reaction
Only when mols of gas doesn’t change during a reaction
k(p) = k(c)
Heterogeneous equilibrium
More than one state exist at equilibrium, solids and liquids are not included in the equilibrium constant expression
