Free Energy and 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. products only products only productfavored product favored weak acids will have a smaller1ha) weak bases will have a smallerlab than strong acids. To determine \(Q\), the concentrations of the reactants and products must be known. c) Discuss the effect of increasing temperature on the extent of the reaction. After finding x, you multiply 0.05 to the 2.0 from 2.0-x and compare that value with what you found for x. For our examples, assign x to the decrease in pressure of each reactant. Our concentrations won't change since the rates of the forward and backward reactions are equal. Categories: . Use equilibrium constant expressions to solve for unknown concentrations. This is because the weaker acid and the weaker base are the most stable species due to their lower potential energies. When you plug in your x's and stuff like that in your K equation, you might notice a concentration with (2.0-x) or whatever value instead of 2.0. How is the Reaction Constant (Q) affected by change in temperature, volume and pressure ? Provide the formula for each ionic compound in the table. Is the reaction spontaneous at 298 K?
