NettetThe instantaneous rate of a reaction at “time zero,” when the reaction commences, is its initial rate. Consider the analogy of a car slowing down as it approaches a stop sign. … NettetThe rate of reaction determined at specified concentration or specified time is called instantaneous rate. The instantaneous rate of the reaction can be determined by measuring concentration of reactant or product at an instant of time and plotting concentration versus time.

NettetThe instantaneous rate is the rate of a reaction at any particular point in time, a period of time that is so short that the concentrations of reactants and products change by a negligible amount. The initial rate is the instantaneous rate of reaction as it starts (as the product just begins to form). NettetInitial Rate: The Method of Initial Rates involves measuring that rank of reaction, r, at very short times before any essential changes in concentration occur.

CHEMICAL KINETICS : THE KEY It is a branch of physical chemistry deals with the "Rate of Chemical Reactions" including the effect of temperature, pressure, concentration, etc., on the rates, and the mechanismbywhich the reactiontakes place. NettetThe rate of a chemical reaction is defined as the rate of change in concentration of a reactant or product divided by its coefficient from the balanced equation. A negative sign is used with rates of change of reactants and a positive sign with those of products, ensuring that the reaction rate is always a positive quantity.

NettetSolution: The rate of a reaction is the change in concentration of the reactant or product divided by the change in time.Therefore, the formula of rate of reaction for the above reaction would be: Rate of reaction = - (1/2)Δ [Na]/Δt = -Δ [Cl]/Δt = + (1/2) [NaCl]/Δt Browse Chemical Kinetics Customize your course in 30 seconds Which class are you in?
