product or reactant favored calculator

To balance an equation, it is necessary that there are the same number of atoms on the left side of the equation as the right. To favor one side or the other indicates the direction that the reaction is going. equilibrium. The equilibrium constant expression is an equation that we can use to solve for \(K\) or for the concentration of a reactant or product. To figure out the position of equilibrium we could look at our pKa values and say, "Alright on the left we have negative two, on the right we have negative three." And we know that the equilibrium, the equilibrium favors the acid with the higher pKa value, favors the formation of the acid with the higher pKa value. The main difference between \(K\) and \(Q\) is that \(K\) describes a reaction that is at equilibrium, whereas \(Q\) describes a reaction that is not at equilibrium. Is the reaction product-favored or reactant-favored? It does, however, depend on the temperature of the reaction. Setting up the Equation for the Equilibrium Constant Examples Video 1 . 1.
