Question

Name Chem 1412 Prelab Section LeChatelier's Principle Date A reaction in equilibri reverse reactions continue to occur as the um is termed a "dynamic equilibrium because the forward and molecules collide with each other. What 1. is the definition of equilibrium with respect to theser when CO is decreased, what causes the equilibrium to be 2. According to LeChatelier, restored? 2CO + O2 2CO2 3. How will the direction of the shift be detected in this experiment? 4. What two ways are concentrations decreased in chemical equilibria? 5. How could you decrease the concentration of Cu2+- in the aqueous equilibrium below? blue colorless yellow 6. Indicators are used as color "sensors" for the concentration of H* ions in a solution. Phenolphthalein changes from colorless in acid (high H') to pink (lower H') in base. When a solution containing carbonate ions is added to this equilibrium, the color becomes more pink. Based on the color, have the H ions increased or decreased? Which direction is the shift? What direction does LeChatelier predict?

Explanation / Answer

1) An equilibrium is a special condition for reversible reaction which established only when the rate of forward reaction become exactly equal to rate of backward reaction. Thus, a continuous conversion of reactant to product (forward reaction) and product to reactant (backward reaction) takes place and as a result of which, no further change in the concentration of the reactant and product occurs. This is why equilibrium is very correctly called as  a dyanmic phenomenon.
