Secondary School Chemistry
Understanding Electrochemical Thermodynamics through Entropy Analysis
Thomas H. Bindel
Pomona High School, 8101 West Pomona Drive, Arvada, CO 80005
Cover
August 2000
Vol. 77 No. 8
p. 1031
Abstract
This discovery-based activity involves entropy analysis of galvanic cells. The intent of the activity is for students to discover the fundamentals of electrochemical cells through a combination of entropy analysis, exploration, and guided discovery. The student is guided into discovering (i) two fundamental quantities that determine the theoretical electrical potential of any galvanic cell, and n, and (ii) the numerical value for the Faraday constant. Then the student makes predictions and tests them experimentally.
Supplement
Materials list, follow-up questions, and tables of cell equations are available.
