1. Reaction Rate Definition

Key Concepts & Definitions

  • Reaction Rate: The measure of how quickly reactants are converted into products in a chemical reaction, typically expressed as the change in concentration per unit time (e.g., M/s).
  • Average Rate: The rate calculated over a specific time interval, representing the overall change in concentration divided by the time elapsed.
  • Instantaneous Rate: The rate at a specific moment during the reaction, found using calculus as the slope of the concentration vs. time curve.
  • Rate of Change: The difference in concentration of reactants or products over a given time period, indicating the speed of the reaction.
  • Sign Convention: Reactant concentrations decrease (negative change), while product concentrations increase (positive change) during the reaction.
