Extent of reaction at equilibrium

WebTo use our pKa values to predict the position of equilibrium we need to find the pKa for the acid on the left and from that we subtract the pKa for the acid on the right. The acid on the left is hydronium and hydronium has a pKA of approximately negative two. The acid on the right, is right here and the pKa for this proton is approximately ... WebJul 1, 2024 · Yes you can't compare extent of reactions directly based on the numerical value of the equilibrium constant. A very good example of this is the comparison of solubility of different salts based on their solubility products. Let's take the example of calcium and silver carbonates:

The extent of reaction is a useful quantity in computations with equilibrium reactions. Consider the reaction 2 A ⇌ B + 3 C where the initial amounts are , and the equilibrium amount of A is 0.5 mol. We can calculate the extent of reaction in equilibrium from its definition Web17-7 K and the extent of reaction K reflects a particular ratio of product concentrations to reactant concentrations for a reaction. A small value for K indicates that the reaction yields little product before reaching equilibrium. The reaction favors the reactants. K therefore indicates the extent of a reaction, i.e., how far a reaction proceeds towards the … people\u0027s choice pharmacy phoenix
