Self-Assessment

    1. What happens to DG° as a reaction proceeds?
    increases
    decreases
    stays the same
    goes to zero
    2. What happens to DG as a reaction proceeds?
    increases
    decreases
    stays the same
    goes to zero
    3. Does a negative DG° favor a reaction in the forward direction?
    yes
    no
    maybe so, depends on reactant concentrations (or amounts)
    maybe so, depends on product concentrations (or amounts)
    maybe so, depends on the amounts of all species present
    4. Does a negative DG favor a reaction in the forward direction?
    yes
    no
    maybe so, depends on reactant concentrations (or amounts)
    maybe so, depends on product concentrations (or amounts)
    maybe so, depends on the amounts of all species present
    5. What (check all that apply) is DGinitial dependent upon?
    DG°
    amounts of reactants but not products
    amounts of products but not reactants
    amounts of both products and reactants
    6. What is the best predictor for reaction spontaneity?
    DS°
    DG
    DG°
    DH°
    7. What sign and magnitude of DG° results in the greatest conversion of reactants to products?
    small positive
    large positive
    small negative
    large negative
