Reversible Reactions and Dynamic Equilibrium
What you need to know
Recall that specific chemical reactions can be entirely reversed by altering the physical or chemical conditions of the reaction environment.
Recognize and utilize the standard mathematical symbol used in chemical equations to denote reversible reactions.
Understand that reversible reactions occurring within closed systems fundamentally do not achieve a 100% yield of products.
Recall that a state of dynamic equilibrium is reached precisely when the rates of the forward and reverse reactions become equal.
Predict the specific effect that changing reaction conditions (such as altering concentration, temperature, and pressure) will have on the final position of equilibrium.
Suggest the most appropriate reaction conditions required to maximize the ongoing production of a specific desired chemical product.
Understand and explain that while catalysts significantly increase the rate of reaction, they inherently do not affect the final equilibrium yield.
Assess the practical, safety-related, and economic disadvantages of utilizing extremely high temperatures or extreme pressures in industrial chemical manufacturing processes.
