Chemical Equilibrium Flashcards
What is the formula for the reaction Quotient?
What is the formula for the reaction Equilibrium constant?
What is the difference between a reaction quotient and an equibrium constant?
Equilibrium constant is the reaction quotient at equibrium
what is chemical equilibrium?
when the concentrations of the products and reactants are unchanged over time
How do you calculate the gas phase equilibria constant?
using partial pressures of gasses
How do you calculate Kp from Kc?
What is the Equilibrium constant of the following reaction?
Solids have an Activity of 1
non-homogenous equilibrium
What is an activity?
Concentration or Partial Pressure to the power of the stochiometric coefficient
How can liquids have an Activity of 1
If the reaction occurs in a liquid that isnt mixed with anything else
eg. reaction occurs in a vessel of pure ethanol.
or 2 immiscible liquids
If the equilibrium constant is Below 1 is the forward reaction or backward reaction favored
Backwards - reactants are favoured
If the equilibrium constant is Larger then 1 is the forward reaction or backward reaction favored
Forwards- products are favoured
What is the Equilibrium constant for the following set of reactions
parallel equilibria
what is the acid dissociation constant of the following reaction
H20 has an activity of 1
Explain LeChatelier’s Principle
If a system at equilibrium is stressed, the system will re-establish the equilibrium to reduce the applied stress
What is Solubility Equilibrium
Whats the Solublilty Equilibria of the following Equation
Equilibria Constant that involves an ionic solid that doesn’t fully dissociate and its consituent ions.
what is the formula of pH?
what is the formula of pKa?
What is equilibrium in terms of free gibbs
What is the Equation for free gibbs at equilibrium
Equilibrium is the state of minimum Free Gibbs Energy
