Unit 12: Thermodynamics - Chapters 16 & 17

Directions:  Questions 1 through 6 are short constructed-response questions that should require about seven minutes each to answer.  Read each question carefully and write your response in the space provided following each question.  Your responses to these questions will be scored on the basis of the accuracy and relevance of the information cited.  Explanations should be clear and well organized.  Specific answers are preferable to broad, diffuse responses.  For calculations, clearly show the method used and the steps involved in arriving at your answers.  It is to your advantage to do this, since you may obtain partial credit if you do and you will receive little or no credit if you do not.  Be sure to write all your answers to the question on the lined pages following the question set.

Note: For all questions, assume that the temperature is 298 K, the pressure is 1.00 atmosphere, and solutions are aqueous unless otherwise specified.

Directions: Each of the questions or incomplete statements below is followed by four suggested answers or completions. Select the one that is best in each case and then fill in the corresponding circle on the answer sheet.
