Q:The properties of scandium
Sci-Scandium (Sc) Basic knowledge Introduction In 1879, Swedish chemistry professor Nelson (LFNilson, 1840 ~ 1899) and Clive (PTCleve, 1840 ~ 1905) were almost simultaneously in rare mineral silica beryllium yttrium and black The mine found a new element. They named this element "Scandium" (scandium), ...
Q:Effect of Catalyst on Chemical Reaction Rate
The catalyst can only change the rate of chemical change (faster or slower), does not change its own quality and chemical properties, nor does it change the amount of reaction product.
Q:Chemical reaction in the presence of catalyst for the reaction are carried out a high life
Some reactions require some of the catalyst that is not needed
Q:Describe the role of a catalyst..........?
a catalyst speeds up the reaction
Q:Chemistry GCSE what is a catalyst?
Enzymes are catalysts in organic and organic strategies. many times catalysts that are used for business or lab reactions are fairly basic compounds. diverse reactions use diverse catalysts, that's because of the various reaction mechanisms. Catalysts take part in a reaction yet end unchanged. Hydrogenation catalysts are factors which includes platinum, nickel and so on. those metals react with the hydrogen on the exterior of them and the different reactant which includes vegetable oil to produce a product. Platinum is is utilized in catalytic converters on automobiles, in spite of the undeniable fact that lead can injury the platinum by potential of blocking off the exterior, subsequently you shouldn't use leaded petrol in automobiles with catalytic converters. Vanadium pentoxide is used to catalyse the reaction of SO2 to SO3 . and so on and so on. So in biology diverse enzymes are required for various reactions, reckoning on the reaction mechanism. Starch hydrolyses to glucose with an enzyme spoke of as ptaylin, cutting-edge in saliva. Proteins choose enterokinase to start the reaction all the way down to amino acids. there are a number of enzymes for various chemical strategies, that shall we not stay to tell the tale without. Animals that graze which includes cows and horses have enzymes cutting-edge of their digestive tract which will ruin down cellulose, we don't, so as that they are in a position to consume grass and so on and extract glucose from it. desire this helps, and not confuses.
Q:Catalyst and Intermediate.?
Cl is the catalyst. ClO the intermediate. The catalyst is the component which does not change in overall reaction. He forms some intermediate component(s) with the reactants. In the later reaction steps the intermediate(s) react forming the catalyst in its original state. (a) The overall order is the sum of the orders with respect to the components: n = 1 +1 = 2 (b) the unit of the rate of reaction is r [=] mol/ (Ls) (more general mol per unit time and volume) compare dimensions mol / (Ls) [=] k · mo/L · mol/L =k [=] L/(s mol) (more general unit volume per unit time and mole) (c) First reaction For elementary reaction steps the order of the reaction rate with respect to a reactant is equal to stoichiometric coefficient. Hence the rate of first reaction is: r₁ = k₁·[Cl]·[O₃] Overall rate is given by the rate determining step, while other reaction steps are in equilibrium: r = r₁ = k₁·[Cl]·[O₃] If second reaction is the rate determine step r₂ = k₂·[O]·[ClO] while reaction 1 is at equilibrium K₁ = ( [ClO]·[O₂] ) / ( [Cl]·[O₃] ) =[ClO] = K₁·( [Cl]·[O₃] ) / [O₂] the overall rate would be: r = r₂ = k₂·[O]·[ClO] = K₁·k₂·[O]·[Cl]·[O₃] / [O₂] = k·[O]·[Cl]·[O₃] / [O₂] That doesn't match the observed rate law
Q:What are catalysts?
Something that can cause a reaction, speed up or slow down a reaction, without changing itself.. structure yea..
Q:How does catalyst aid a chemical reaction?
it makes the reaction go faster.
Q:What is the difference between biological and chemical catalysts?
Biological catalysis involves an enzyme usually working in conjunction with a co-enzyme. These enzyme/co-enzyme systems are highly specific and are usually only effective for one reaction. Catalysis of non biological reactions is usually much more general and any one catalyst will be effective in many reactions.
Q:The quality and nature of the catalyst before and after the chemical reaction did not change this sentence wrong?
This sentence is true, ah, may practice mistakes in the bar.
