Rate of reactions chemistry

• The main components of the learning process are attention, encoding, storage, and retrieval.
• The rate equation is the mathematical expression that relates the reaction rate to the concentrations of reactants.
• The rate determining step is the slowest step in a reaction mechanism that controls the overall rate of reaction.
• Factors that affect the rate determining step will have the greatest influence on the rate of reaction.
• Rate equations can be derived from the balanced chemical equation using stoichiometric coefficients.
• Factors affecting the rate of a reaction include temperature, concentration, surface area, catalysts, and pressure (for gas phase reactions).
• Rate equations can be derived from the balanced chemical equation using stoichiometric coefficients as exponents.
• Increasing temperature increases the kinetic energy of particles, increasing their collisional frequency and probability of successful collisions.
• Enzymes act as biological catalysts, speeding up biochemical reactions without being consumed or altered themselves.
• Concentration affects the likelihood of successful collisions between reactant molecules.
