    Study Notes

    • Chemical reactions are influenced by factors like reactant concentration, temperature, and catalyst presence.
    • Reactant concentration plays a crucial role in reaction rate, with higher concentrations leading to faster reactions.
    • Activation energy is the energy required for a reaction to occur, with higher activation energy leading to slower reactions.
    • Most chemical reactions are reversible, with forward and reverse reactions happening simultaneously.
    • Dynamic chemical equilibrium occurs when the rates of forward and reverse reactions are equal, leading to constant concentrations of reactants and products over time.
    • Equilibria can strongly favor either the products or the reactants, depending on the specific reaction.
    • Our bodies maintain equilibrium in many reactions to ensure survival, favoring one side over the other.
