How does Keq relate to KSP?
Ksp stands for solubility product constant while Keq stands for equilibrium constant. The key difference between Ksp and Keq is that the term Ksp describes the solubility of a substance, whereas the term Keq describes the equilibrium state of a particular reaction.
What is the equilibrium constant for Fescn?
1.50 x 10-4 M.
By spectroscopy and Beer’s Law, it is found that [FeSCN2+] at equilibrium is 1.50 x 10-4 M.
What does it mean when Keq is equal to 1?
If Keq = 1, then the position of equilibrium is in the center, the amount of products is roughly equal to the amount of reactants at equilibrium.
When can you assume activity coefficient is 1?
A species’ activity coefficient corrects for any deviation between its physical concentration and its ideal value. For a gas, a pure solid, a pure liquid, or a non‐ionic solute, the activity coefficient is approximately one under most reasonable experimental conditions.
How do you know if KEQ favors reactants or products?
If Q>K, then the reaction favors the reactants. If Q
Are KEQ reactants over products?
Equilibrium Constant Expressions The equilibrium constant value is the ratio of the concentrations of the products over the reactants. If Keq is very small, the concentration of the reactants is much greater than the concentration of the products.
What if Keq is greater than 1?
If Keq is greater than 1, it means the concentrations of the products are greater than those of the reactants. If Keq is less than 1, it means the concentrations of the reactants are greater than the products.
Can activity coefficient be greater than 1?
The activity coefficient can be higher than 1. This is not a problem at all. Typically, activity coefficients for polar compounds as water and alcohols (methanol, ethanol, propanol, butanol, etc…) are larger than the unity because the system is strongly non-ideal.
