Each pre-class Podia question is based on the pre-class material and working through the pre-class material will help you formulate your response. Consider the problem and write down/draw out your solution in your class notebook. These questions are designed to hone your skills so that you can analyze and solve mastery problems you will encounter throughout the course.

Two days before the next whole-class session, the pre-class Podia question will become visible in Podia, where you can click on the prompt and submit your answer.

Submissions for pre-class Podia activities are due 1 hour before the start of your whole-class. Be sure to submit your response before the due time.

Day 21 Pre-Class Podia Activity

Amino acids were the first chemical compounds of biological interest produced in an experiment simulating conditions on the primitive Earth. These substances have been produced using an electrical discharge through different types of simple mixtures, such as H2O/CH4/NH3/N2, H2O/CH4/NH3/N2, and CO/N2/H2. Ball and stick models of six different amino acids are as follows:

Based on your analysis of their composition and structure, arrange these amino acids in order of increasing standard molar entropy. Provide a brief rationale for your ordering, using ideas related to energy dispersal.
