Temperature Formula:
From: | To: |
Definition: This calculator determines the temperature of a chemical reaction based on Gibbs free energy and the equilibrium constant.
Purpose: It helps chemists and chemical engineers understand the temperature conditions needed for specific reaction equilibria.
The calculator uses the formula:
Where:
Explanation: The formula relates the thermodynamic driving force (Gibbs energy) to the equilibrium position at a given temperature.
Details: Knowing the reaction temperature helps in designing chemical processes, predicting reaction feasibility, and optimizing conditions.
Tips: Enter Gibbs free energy in Joules and equilibrium constant in mol/m³. The equilibrium constant must be > 0.
Q1: What is Gibbs Free Energy?
A: It's a thermodynamic potential that measures the maximum reversible work a system can perform at constant temperature and pressure.
Q2: What units should I use for the equilibrium constant?
A: The calculator expects Kc in mol/m³. Convert if using different units.
Q3: Why is the natural logarithm not used?
A: The formula uses base-10 logarithm (log10) as it's commonly used in equilibrium constant expressions.
Q4: Can I use this for any reaction?
A: Yes, as long as you have accurate values for ΔG and Kc at the desired conditions.
Q5: What does a negative temperature result mean?
A: Negative temperature values are physically impossible. This indicates an error in input values or that the reaction is not feasible.
