KINETICS describes the range and mechanism of response give that it occurs. Thermodynamics says if. Kinetics says how and how fast. REACTION RATES regularize is mensural as amount of money /time. Ex. Rate of speed is maintain/time: speed = 25 mi/hr. RATE OF A REACTION = RATE OF disappearance OF REACTANTS OR RATE OF bearing OF PRODUCTS Rate of response go away be expressed as a rate of change in dousing in a constant volume: the whole of rate will be moles/L?s. (Moles per liter per second) In a chemical substance reactio n like A + B ? C (DESIGNATION: [ ] government agency preoccupancy) Initially, the [A] and [B] is very senior high school; [C] is 0. Rate is very fast. As the reaction proceeds, [A] and [B] starts to get smaller; [C] increases. Rate slows. At the end, [A] and [B] = 0; [C] is high and when A and/or B run out, the reaction stops. Rate is 0.

THE RATE OF A REACTION IS DEPENDENT ON THE CONCENTRATION OF THE REACTANTS ONLY, NOT THE CONCENTRATION OF THE PRODUCTS. When one of the reactants runs out, the reaction stops. The rate of reaction A + B ?C is represented as the change magnitude of reactant molecules wit h time and as the increase of product C mol! ecules with time. Reactants A&B Products C 01/29/2003 CHEM. 2AP UNIT 10 CH. 12 2 Kinetics When you finish this section you will be able to use concentration vs. time info to visualise relative reaction rates. Your textbook defines the rate of a reaction as: rate = change in concentration of a substance change in time The rate of a reaction is a measure in terms of change...If you motivation to get a full essay, order it on our website: BestEssayCheap.com
