Rate of Reaction The fundamental concept in kinetics is the Rate of Reaction, which is the change in concentration of a reactant or product per unit of time. Disappearance: As the reaction proceeds, the concentration of reactants decreases (negative rate).  • Appearance: The concentration of products increases (positive rate) Arrhenius Equation This equation mathematically expresses how the rate constant (k) depends on temperature (T) and activation energy (E_a): Molecularity: The number of reacting species (atoms, ions, or molecules) that must collide simultaneously in an elementary step. It is a theoretical concept and is always a whole number (1, 2, or rarely 3) Order: The sum of powers in the rate law (x + y). It is an experimental value and can be zero or a fraction Molecularity vs. Order Rate Law and Order of Reaction The Rate Law is a mathematical equation that links the reaction rate with the concentrations or pressures of the reactants.  For a general reaction aA + bB \rightarrow Products: • k: The Rate Constant (specific to the reaction and temperature).  • x and y: The Order of Reaction with respect to A and B. These must be determined experimentally; they do not always match the stoichiometric coefficients (a and b).
