Q:What is the analytical principle of chemical adsorbents?
What do you mean by the chemical adsorber? BET is the use of the surface of the uneven force field, but the inert gas at low temperature in the surface adsorption. TPD, TPR is the number of active centers that can be measured by the technique of desorption and reduction between specific gases and catalysts as the temperature increases. If the active site is a reduced position, H2-TPR can be used. If the active site is acidic, NH3-TPD can be used, but also the method of alkali titration.
Q:how does the AMOUNT of a catalyst affect reaction rate?
theoretically, the more catalyst there is, the faster the rate of reaction. this is because it is bringing more particles together quicker.
Q:On the issue of chemical balance and catalyst
The catalyst can only improve the equilibrium speed, reducing the time to reach equilibrium, but will not affect the chemical balance.
Q:Chemical common sense about the catalyst
Chemical reactions are generally contact reaction, of course, the more contact with the faster response, pore structure is to increase the contact area
Q:Explain, using an example, how a heterogeneous catalyst works?
Because of the production of photochemical oxidants from NOx reacting with hydrocarbons in sunlight Noxer blocks are used to rid the NOx from the surroundings through The titanium dioxide (TiO2) on the bocks absorbs ultra-pink radiation from daylight which excites its electrons to a bigger orbital. On the outside of the crystals of TiO2 a reaction happens between oxygen and a high power electron from the TiO2. O2 + e־ --O2 ־ The excessive vigor electron is then given back to the TiO2 when water then reacts with the oxygen to present H2 O + O2 --H+ + O2 ־ + OH Nitrogen dioxide is oxidised to nitrate ions as a result of the hydroxyl radical being an awfully strong oxidising agent NO2 + OH --H+ + NO3 ־ The superoxide from response 3 also varieties nitrate ions from nitrogen monoxide. NO + O2 ־ --NO3 ־ This nitrate is washed away through rain or combines with the concrete within the block.
Q:Why are transition metals more likely to be catalysts?
there are so much catalysts made up of transition metals. because one of the characteristics of transition metals is can be made to catalyst. one of the catalyst that is mostly used is iron fillings which is used as catalyst to make ammonia from nitrogen gas and hydrogen gas.
Q:how a catalyst can provide a new route in forming the product?
A catalyst may provide a new route in forming a product. Often the reactants have too much energy and bounce off of each other forming few products. The catalyst may provide a surface where the reactants can settle momentarily in close proximity completing the reaction at an increased rate. The catalyst has been pictured (for illustration only) as a surface filled with grooves and when the reactants settle within the grooves (forming a film?) they are close enough to react rather than bounce off of each other. As such the catalyst facilitates the reaction without being used up in the reaction. The catalyst may become 'poisoned' with other molecules that interfere with the desired reaction and the reactants may have to be relatively pure to protect the catalyst.
Q:Does a catalyst have an effect on the Gibbs free energy of a reaction?
A catalyst can change the activation energy not the Gibbs energy. The Gibbs energy is the energy difference between the initial state and final state. A catalyst cannot change that. Imagine you are driving from school to home. How you drive do not change the height difference between the school and your home. However, a catalyst can change your path which can change the routine you drive from school to home. So if there is a hill in between your school and you home, you have the choice to drive through it or drive around. Here is a picture: upload.wikimedia.org/wikipedia/co... A catalyst can change the height of the barrier, but cannot alter the initial or final state.
Q:Will the catalyst in the chemical reaction be reduced?
The amount of catalyst in the chemical reaction is not reduced, the catalyst is divided into a positive catalyst and a negative catalyst, the positive catalyst promotes the reaction, and the negative catalyst inhibits the reaction
Q:The greater the chemical adsorption strength, the catalyst activity changes
If the adsorbent is a reactant, then the better the adsorption capacity of the better catalytic effect; but the catalyst surface of the product will generally have adsorption, if this effect has become very strong, then desorption The process will become difficult, the catalytic effect will decline; the other one, if the adsorption of other substances, such as the reaction may produce a reaction or the catalyst will poison the material, it is greatly detrimental to the catalytic effect. The effect is to be controlled in a suitable optimum range for superior, and preferably to be selectively adsorbed.
