Hi! Can someone answer Learning Task 1? Explain the required answers briefly. Thanks !
IV. LEARNING PHASES AND LEARNING ACTIVITIES 1. Introduction (Time Frame: 30 minutes) Equilbrium is a balanced condition. A body in stable equilbrium will return to its previous state of equilibrium if it is disrupted. In a chemical reaction, the concentrations of reactants and products remain stable and there are no visible shifts in the environment when it reaches equilibrium. However, since reactant molecules continue to form product molecules when product molecules react to yield reactant molecules, there is a lot of activity at the molecular level. At the end of the lesson, you will be able to: 1. Explain chemical equilibrium in terms of the reaction rates of the forward and the reverse reaction; 2. Calculate equilibrium constant and the pressure or concentration of reactants or products in an equilibrium mixture; and 3. State the Le Chatelier's principle and apply it qualitatively to describe the effect of changes in pressure, concentration, and temperature on a system at equilibrium. What is your favorite carbonated drink? Did you know that in a carbonated drink, carbon dioxide is pUshed into the solution by adding pressure? Carbonic acid is formed when carbon dioxide reacts with water, as seen in the equation below: CO2 + H2O H2CO3 Carbon dioxide is released from the decomposition of carbonic acid when the container is opened and the pressure is released. H2CO3 - CO2 + H2O What do you notice from the two reactions? The two reactions are the reverse of each other and can be written as: CO2 + H2O H2CO3 This is referred to as a reversible reaction. A reversible reaction is one that can go in both directions. If the rates of forward and backward reactions are identical, chemical equilibrium exists. Learning Task 1 Give an example of a chemical reaction in chemical equilībrium. Define chemical equilibrium using your chemical equation.
