KINETICS describes the range and mechanism of reply given up that it occurs. Thermodynamics says if. Kinetics says how and how fast. REACTION RATES treasure is mensurable as amount of money /time. Ex. Rate of speed is duration/time: speed = 25 mi/hr. RATE OF A REACTION = RATE OF disappearance OF REACTANTS OR RATE OF bearing OF PRODUCTS Rate of response pass on 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 chemic response like A + B ? C (DESIGNATION: [ ] substance immersion) Initially, the [A] and [B] is very highschool; [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 ebb of reactant molecules with time and as the increase of product C molecules 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 position relative reaction rates. Your textbook defines the rate of a reaction as: rate = change in concentration of a substance change in time The rat e of a reaction is a measure in terms of cha! nge...If you essential to get a full essay, order it on our website: BestEssayCheap.com
