Webb5 dec. 2024 · Little’s Law is a theorem that determines the average number of items in a stationary queuing system, based on the average waiting time of an item within a system and the average number of items arriving at the system per unit of time. The law provides a simple and intuitive approach for the assessment of the efficiency of queuing systems. WebbRate Constant or Velocity Constant. Consider a rate of reaction, aA+bB→cC+dD. where, a, b, c and d are the stoichiometric coefficients of reactants and products. The rate expression for this reaction is, Rate∝A xB y. where exponents x and y may or may not be equal to the stoichiometric coefficients (a and b) of the reactants.

Note: Ordinary rate law is a differential rate equation because it shows the instantaneous rate of the reaction.
