Equilibrium

(Lecture id-1121)

TOPICS & OBJECTIVES

1010 - Reaction Quotient
    1010 - Define reaction quotient (Q).
    1020 - Recognize Q changes as a reaction progresses but K does not (at a given temperature).
    1030 - Use Q to determine the direction in which a reaction will progress, given K.
    1040 - Use Q to measure reaction progress towards equilibrium.
 
1020 - Equilibrium Concentrations
    1010 - Undestand an ICE table reveals how a reaction changes from initial to equilbrium concentrations.
    1020 - Use ICE tables to relate equilibrium concentration to initial conditions using a single variable (x).
    1030 - Determine equilibrium concentrations given a K value and one or more equilibrium concentrations.
    1040 - Use ICE tables to relate the equilibrium concentrations, initial concentrations and K.
    1050 - Apply the x is small aproximation to simplify a solution.
    1060 - Know the x is small approximation is valid if x is less than 5% of the concentration compared.
 
1030 - Disturbing Equilibrium
    1010 - Recognize that disturbing a reaction at equilibrium changes Q to a value other than K.
    1020 - State Le Chateliers principle, that a system disturbed from equilibrium will return to equilibrium (Q will return to K).
    1030 - Predict how equilibrium shifts as concentration, presssure or volume of a reaction are disturbed.
    1040 - Predict how K changes with temperature (T) for an exothermic or endothermic reaction.
