Reversibility

(Lecture id-1120)

TOPICS & OBJECTIVES

1010 - Reversible Reactions
    1010 - Recognize a reversible reaction has both a forward and reverse reaction rate.
    1020 - Predict how the forward and reverse rates may change as a reaction proceeds.
    1030 - Recognize that when forward and reverse rates become equal the reaction is at equilibrium.
 
1020 - Equilibrium Constant
    1010 - Recognize that at equilibrium quantities of reactants and products may not be equal.
    1020 - Use the law of mass action to determine K, a reactions ratio of reactants to products at equilibrium.
    1030 - Understand the ratio K is always true for a given reaction at equilibrium (at a given temperature).
    1040 - Interpret the value of K to determine whether equilibrium favors products or reactants.
    1050 - Describe how K changes if you reverse, multiply by a constant, or add chemical equations.
 
1030 - Heterogeneous Equilibrium
    1010 - Express and interpret the equilibrium constant in terms of gas pressure (Kp) or concentration (Kc).
    1020 - Relate Kp to Kc using the ideal gas law : Kp = Kc (RT)^Δn where Δn = (c+d)-(a+b)
    1030 - Understand units are omitted for K by convention, but values are assumed to be in M and atm.
    1040 - Know the concentration of pure solids & liquids do not change in a reaction and are not included in the equilibrium expression.
    1050 - Write and interpret an equilibrium expression for a reaction involving a solid or liquid.
 
1040 - WORKING
    1020 - Draw and interpret a reaction coodinate diagram including the energy of the reactants, transition states, intermediaries, and products.
    1070 - Show a mechanism is consistent with an observed rate law.
