FAQs
1. What is Kp in chemistry?
Kp is the equilibrium constant for gaseous reactions based on partial pressures. It indicates the ratio of product pressures to reactant pressures at equilibrium.
2. How do you calculate Kp?
Kp is calculated using the formula: Kp = (Pproducts^n) / (Preactants^m), where P is the partial pressure and n/m are stoichiometric coefficients.
3. Why is Kp important?
Kp is essential for understanding the equilibrium position of a reaction and predicting how changes in pressure or concentration affect the reaction.
4. Can Kp be negative?
No, Kp cannot be negative. It is always a positive value, as it represents a ratio of pressures.
5. Does temperature affect Kp?
Yes, Kp depends on temperature. An increase or decrease in temperature can shift the equilibrium position and alter the Kp value.
6. What units are used for Kp?
Kp is unitless or expressed in atm, depending on the reaction's stoichiometry and partial pressures.
7. How does Kp differ from Kc?
Kp is based on partial pressures, while Kc is based on molar concentrations. They are related through the ideal gas law.
8. What is the relationship between Kp and Kc?
Kp = Kc(RT)^Δn, where R is the gas constant, T is temperature, and Δn is the change in moles of gas.
9. How does stoichiometry affect Kp?
Stoichiometry determines the exponents in the Kp formula, directly affecting the calculation.
10. Can Kp be calculated for non-gaseous reactions?
No, Kp is specifically used for gaseous reactions involving partial pressures.
