How do I check if a reaction is spontaneous?

You can use the `calculate_gibbs_energy` tool. If the resulting $\Delta G$ is negative, the reaction is spontaneous.

Can I predict the temperature where a reaction becomes non-spontaneous?

Yes, use the `find_spontaneity_range` tool to determine the temperature bounds for spontaneity.

What happens at the equilibrium temperature?

At the equilibrium temperature, $\Delta G$ is zero, meaning the reaction is at the transition point between spontaneous and non-spontaneous.

More Details Connect to Claude

This MCP server provides tools to analyze chemical reaction spontaneity. It uses the Gibbs free energy equation to calculate $\Delta G$, determine temperature ranges for spontaneity, and identify equilibrium temperatures. Use calculate_gibbs_energy to find the energy change, find_spontaneity_range to find temperature bounds, calculate_equilibrium_temperature for the transition point, and predict_phase_impact to evaluate how phase changes affect the system.
