SC2 Students will relate how the Law of Conservation of Matter is used to determine chemical composition in compounds and chemical reactions. f. Explain the role of equilibrium in chemical reactions. . What causes chemical reactions to attain equilibrium? .
f. Explain the role of equilibrium in chemical reactions.
What causes chemical reactions to attain equilibrium?Georgia Performance Standards & Essential Questions:
Chemical equilibrium occurs when a reaction and its reverse reaction proceed at the same rate.
Although time continues to pass, the numbers of reactant and product molecules are the same as in (c). No further changes are seen as time continues to pass. The system has reached equilibrium.
The reaction continues as time passes and more reactants are changed to products.
The reaction begins to occur, and some products (H2 and CO2) are formed.
Equal numbers of moles of H2O and CO are mixed in a closed container.E. Chemical Equilibrium: A Dynamic Condition
If Q > K, then there is too much product, and the equilibrium shifts to the left.
If Q < K, then there is too much reactant, and the equilibrium shifts to the right.
