9. Human saliva has a pH value of approximately 6.8, and can be considered a: a. strong base K weak acid c. strong acid d. weak base 10. The following reaction will occur: a. non -spontaneously b. spontaneously c. reaction is temperature dependent 11. The following reaction a. occurs spontaneously b. is temperature dependent C. occurs non -spontaneously 12. Which of the following adjustments would NOT cause a reaction to proceed faster? a. changing all reactants to the liquid phase b. increasing the temperature of the reaction c. using a greater amount (high concentration) of reactants d. using only covalent reactants 13. All of the following reaction conditions would generally increase the rate of a chemical reaction, EXCEPT: a. changing the reactants from a liquid state to a gas state. b. increasing the temperature of the reaction c. addition of a catalyst d. increasing the concentration of the reactant species
