If K, is 1.6*10 for the reaction 2HS2H₂ Sa what is the equilibrium constant for the chemical reaction H+SHS? (4 pts) a. 1.6*10-2 b. 62.5 c. 7.91 d. 31.3 e. 0.127 If the reaction quotient (Q) is greater than K, the reaction will do what? (4 pts) Go towards reactants. Go towards products. The reaction quotient is always equal to K. Temperature will always increase. «Volume will always decrease. The conjugate acid of Aniline has a K, of 2.3 10. What is the K, of Aniline? (4 pts) a. 1.0 10-14 b. 4.3 104 c. 1.0 10.7 d. 4.3 10-10 e. None of the above. in A solution with potassium acetate KC,H,O, Sodium nitrate NaNO,, and sodium fluoride NaF, will qualitatively be what pH? (4 pts) Acidic, pH greater than 7. Basic, pH greater than 7. Acidic, pH less than 7. Basic, pH less than 7. «Neutral pH exactly 7. Cannot determine qualitatively. in Calculate the ratio of weak acid to its conjugate base ([HA[A-]) needed to make a 4.70 pH solution using benzoic acid (K, -6.40*10'), (4 pts) a. 3.2 b. 2.0 10.5 c. 5.0 104 d. 6.4 10-5 c.0.31 Which statement(s) is/are true for a buffer solution? (4 pts) They are made up of a weak acid/base conjugate pair. The less concentrated the buffer solution the larger the buffer capacity. They will absorb a certain quantity of H+ or OH- without large changes in pH. Two of the above are correct. a-c are all correct. There are no correct statements.
