CHM135H1 Lecture : Calculating Entropy and Enthalpy (Medium)

Use the observations about each chemical reaction in the table below to decide the sign (positive or negative) of the reaction enthalpy Delta H and reaction entropy Delta S . Note: if you have not been given enough information to decide a sign, select the "unknown" option.

9. (#3.14) Decarboxylation of pyruvic acid (C,H,O.) yields acetaldehyde (C,H,O). Calculate the change in enthalpy, entropy, and Gibbs free energy for this reaction.
