WebPartition coefficient. In the physical sciences, a partition coefficient ( P) or distribution coefficient ( D) is the ratio of concentrations of a compound in a mixture of two immiscible solvents at equilibrium. This ratio is therefore a comparison of the solubilities of the solute in these two liquids. The partition coefficient generally ...

WebQ is used to determine whether or not the reaction is at an equilibrium. At any given point, the reaction may or may not be at equilibrium. By calculating Q (products/reactants), you can compare it to the K value (products/reactants AT EQUILIBRIUM) to see if the reaction is at equilibrium or not. If Q=K, the reaction is at equilibrium. spid thames waterWebThe coefficients in the equation tell us that 1 1 mole of \ce {Fe2O3} FeX 2OX 3 reacts with 2 2 moles of \ce {Al} Al, forming 2 2 moles of \ce {Fe} Fe and 1 1 mole of \ce {Al2O3} AlX … spid texasWebAug 18, 2024 · Balance the remaining atoms, usually ending with the least complex substance and using fractional coefficients if necessary.
