Essential question: How do energy and entropy combine to predict chemical direction?
A process can be spontaneous even when it absorbs heat.
Build an initial model and explanation for: How do energy and entropy combine to predict chemical direction?
Record observations, questions, an initial model, and one claim that could be tested. Use these concepts where relevant: Gibbs free energy; enthalpy; entropy; spontaneity; coupling.
Study and explain the week's core ideas: Gibbs free energy; enthalpy; entropy; spontaneity; coupling
Open thermodynamics introduction.
Revise Monday's model. Add two evidence-backed annotations and explain one limitation or uncertainty.
Use ΔG=ΔH−TΔS in Extended pathway; interpret signs in Core.
Show units, setup, calculation or graph reasoning, then write what the quantitative evidence can and cannot establish about: How do energy and entropy combine to predict chemical direction?
Free-energy graph/data analysis.
Use the course safety charter. If supervision, facilities, materials, or conditions are not appropriate, use the supplied-data/simulation alternative rather than improvising hazardous procedures.
Record variables or design constraints, procedure/model, observations/data, and one revision you would make after reviewing the evidence.
Answer the essential question: How do energy and entropy combine to predict chemical direction?
Submit a claim, at least two specific pieces of evidence, reasoning that connects them, one limitation/counterclaim, and a correction note for any essential concept below 80%.
Select one artifact from this week and explain why it is trustworthy evidence of growth.
