How to calculate Kp in chemistry?
Understand the Problem
The question is asking how to calculate Kp, which is the equilibrium constant for gas-phase reactions expressed in terms of the partial pressures of the reactants and products. This requires an understanding of the relationship between Kp and the reaction's stoichiometry.
Answer
Kp = (partial pressures of products) / (partial pressures of reactants) raised to respective coefficients
The final answer is to use the formula Kp = (partial pressures of products) / (partial pressures of reactants), raised to the power of their respective stoichiometric coefficients.
Answer for screen readers
The final answer is to use the formula Kp = (partial pressures of products) / (partial pressures of reactants), raised to the power of their respective stoichiometric coefficients.
More Information
Kp is useful for reactions involving gases. It depends on the partial pressures and is independent of the initial concentrations.
Tips
Ensure all partial pressures are in the same units and correctly balance the chemical equation.
