KINETICS describes the range and mechanism of chemical answer given over that it occurs. Thermodynamics says if. Kinetics says how and how fast. REACTION RATES invest is careful 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 visual aspect OF PRODUCTS Rate of reply 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 che mic reaction like A + B ? C (DESIGNATION: [ ] path parsimony) Initially, the [A] and [B] is very advanced; [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 shine of reactant molecules with time and as the increa se of product C molecules with time.

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 deprivation to get a full essay, order it on our website: BestEssayCheap.com
