## Description

This MCP server provides a suite of tools to calculate fundamental thermodynamic properties of chemical reactions. It allows users to determine enthalpy changes (ΔH), entropy changes (ΔS), Gibbs free energy (ΔG), and equilibrium constants (K) at specific temperatures. The server accounts for heat capacity and phase transitions to ensure accurate predictions of reaction spontaneity. Use `query_reaction_properties` to get a full thermodynamic profile, `calculate_equilibrium_constant` for equilibrium values, `get_standard_state_data` to look up species properties, and `predict_phase_change_impact` to evaluate how phase shifts affect reaction spontaneity.

## Frequently Asked Questions

**How do I calculate the spontaneity of a reaction?**
You can use the `query_reaction_properties` tool. It calculates the Gibbs free energy (ΔG); if the result is less than zero, the reaction is spontaneous.

**Can I account for phase transitions in my calculations?**
Yes, by providing phase transition data to the `query_reaction_properties` tool or using `predict_phase_change_impact` to see how transitions affect spontaneity.

**Where can I find standard state data for specific chemicals?**
Use the `get_standard_state_data` tool by providing the chemical formula to retrieve enthalpy, entropy, and heat capacity.
