How do I predict a shift caused by adding more reactant?

You can use the `predict_concentration_shift` tool. Provide the current reactants and products, then specify the component being added in the disturbance object.

How does temperature affect an exothermic reaction?

For an exothermic reaction, increasing the temperature will shift the equilibrium toward the reactants. You can verify this using `predict_temperature_shift`.

Can I predict shifts in gas-phase reactions due to pressure changes?

Yes, the `predict_pressure_shift` tool allows you to input the moles of gaseous reactants and products to determine the shift direction when pressure is increased or decreased.

More Details Connect to Claude

This MCP server provides tools to predict how a chemical system at equilibrium responds to external disturbances. By applying Le Chatelier's Principle, the server calculates the direction of the equilibrium shift when concentration, pressure, or temperature is altered. Use predict_concentration_shift to analyze changes in component amounts, predict_pressure_shift for gas-phase pressure changes, and predict_temperature_shift to determine how thermal changes affect the reaction based on its enthalpy.
