How do I calculate the reaction direction?

Use the `calculate_reaction_quotient` tool. By providing the current species states and the equilibrium constant, the tool determines if the reaction is in equilibrium, moving forward, or moving in reverse.

Can I convert Kc to Kp?

Yes, you can use the `convert_kc_to_kp` tool by providing the Kc value, the temperature in Kelvin, and the change in moles of gas (delta N).

How do I find final concentrations?

Use the `solve_equilibrium_concentrations` tool. Input the initial amounts, the stoichiometric roles, and the equilibrium constant to predict the final concentrations or pressures.

More Details Connect to Claude

A specialized computational engine for chemical equilibrium. This MCP server provides tools to calculate the equilibrium constant (Kc or Kp), determine the reaction quotient (Q) to predict reaction direction, and solve for final species concentrations given initial conditions. It handles gaseous and aqueous species, accounting for phase behavior and temperature dependence via convert_kc_to_kp.
