    Study Notes

    Reaction Equilibrium Shift

    • When the concentration of reactants is excessively high, the system is not at equilibrium.
    • To achieve equilibrium, the system needs to convert some products back into reactants.
    • This shift towards the reverse direction (from products to reactants) is necessary to balance the system.
    • The reaction proceeds in reverse from right to left to establish equilibrium.
    • If the concentration of reactants is too large, products must be converted to reactants to reach equilibrium.
    • The system proceeds in the reverse direction (from right to left) to achieve equilibrium.

    Description

    This quiz covers the concept of reaction equilibrium shift in chemical systems. It explores how an increase in the concentration of reactants can disrupt equilibrium and necessitate a shift towards products. Understanding this balance is crucial in mastering reaction dynamics.
