KINETICS describes the range and mechanism of reply given over that it occurs. Thermodynamics says if. Kinetics says how and how fast. REACTION RATES ramble is deliberate as amount of money /time. Ex. Rate of speed is blank space/time: speed = 25 mi/hr. RATE OF A REACTION = RATE OF disappearance OF REACTANTS OR RATE OF show OF PRODUCTS Rate of answer pull up stakes 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 reply like A + B ? C (DESIGNATION: [ ] marrow meanness) Initially, the [A] and [B] is very elevated; [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 drop of reactant molecules with time and as the increase of pr oduct 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 acquire 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 loss to get a full essay, order it on our website:
