Learning Goals Name: Becka Bailey Period: 3rd Please respond below (in the white space) by writing the learning goal, then rank your level of mastery and the give/ teach the learning goal information. Learning Goal #1
● Learning goal
○ Examine the concept of equilibrium
● Mastery
○ rank your understanding from 1 = no understanding, totally confused to 5 = full understanding, I can teach others
○ 4.5
● Critical Information/ Explanation
○ (be specific ­ not one word reply)
○ chemical equilibrium occurs when a reaction and its reverse reaction proceed at the same rate
○ As a system approaches equilibrium, both the forward and reverse reactions are occurring
○ At equilibrium, the forward and reverse reactions are proceeding at the same rate Learning Goal #2
● Learning goal
○ Describe the ratio of the stoichiometry
■ kc [C]c [D]d
[A]a[B]b
● Mastery
○ rank your understanding from 1 = no understanding, totally confused to 5 = full understanding, I can teach others
○ 3
● Critical Information/ Explanation
○ (be specific ­ not one word reply)
○ The ratio of the rate constants is a constant at that temperature and the expression becomes
■ Keq = Kf
Kr

○ Because pressure is proportional to concentration for gasses in a closeds system, the equilibrum expression can also be written as…
■ kp= (PC)c (PD)d
(PA)a (PB)b
○ Kp=Kc(RT)△n
■ △n=(moles of gaseous product)­(moles of gaseous reactant) Learning Goal #3
● Learning goal
○ Discuss the magnitude and direction of the equilibrium constant
■ K c = [C]c [D]d
[A]a [B]b ● Mastery
○ rank your understanding from 1 = no understanding, totally confused to 5 = full understanding, I can teach others
○ 2.75
● Critical Information/ Explanation
○ (be specific ­ not one word reply)
○ The equilibrium constant of a reaction in the reverse reaction is the reciprocal of the equilibrium constant of the forward reaction
○ The equilibrium constant of a reaction that has been multiplied by a number is the equilibrium constant raised to a power that is equal to that number Learning Goal #4
● Learning goal
○ Consider homogeneous and heterogeneous equilibria
● Mastery
○ rank your understanding from 1 = no understanding, totally confused to 5 = full understanding, I can teach others
○ 3
● Critical Information/ Explanation
○ (be specific ­ not one word reply)
○ homogeneous equilibria­all reactants and products are present in the same phase
○ heterogeneous equilibria­ one or more reactants or products are present in a different phase

Learning Goal #5
● Learning goal
○ The value of an equilibrium constant can be calculated using equilibrium concentrations of reactants and products
● Mastery
○ rank your understanding from 1 = no understanding, totally confused to 5 = full understanding, I can teach others
○ 3
