Q:What is the difference between electrocatalysis and general chemical catalysis?
General chemical catalysis is a catalyst, and electrocatalysis also need to be carried out under the conditions of the electric field
Q:Could God be Discribed as a Catalyst?
On reflection, I would say no, God can't be described as a catalyst. That would be like calling a farmer who fertilizes his crop a catalyst; whereas it's the fertilizer that is the catalyst. Or it would be like a scientist in a lab adding an enzyme to something to speed a process; and then having us label the scientist as the catalyst. So in the same way, God doesn't seem to be the actual catalyst; maybe the spirit is the catalyst....
Q:A catalyst?
Does not become part of the chemical change. I am guessing that this is a multiple guess test and the answer you are looking for is D.
Q:The best use of chemical catalysts
Do not know what you want to use the best thing is what the catalyst is generally used in the process, there will be an initial induction period, the catalytic activity is relatively low, and then reached a stable catalytic state, this paragraph is generally called the catalyst life, the final Due to poisoning, active ingredient aggregation and so on factors, the catalyst activity will be reduced, then need to replace the new catalyst
Q:What is the difference between a catalyst and an inducer in a chemical reaction?
The catalyst does not participate in the reaction, but only the carrier of the reaction; the inducer will participate in the reaction
Q:Chemical common sense about the catalyst
Because of the chemical reaction, the larger the contact area, the faster the reaction rate, therefore, the catalyst has a large surface area or pore structure, are to increase the contact area of the catalyst and reactants.
Q:Several experiments were carried out using catalysts
Hydrogen peroxide in the manganese dioxide as a catalyst for decomposition reaction: 2H2O2 == MnO2 == 2H2O + O2 ↑ (laboratory oxygen principle)
Q:What is the microcosmic principle of the catalytic reaction in the chemical reaction?
It is actually directly involved in the reaction, but, after the reaction, it has become a product out, the equivalent of no response
Q:What are the roles of enzymes (protein catalysts) in catalyzing biochemical reactions in the cell.?
To make it simple unlike the dude above me...enzymes (biological catalysts) lower the activation energy, which speeds up the reaction. EVERY reaction needs a little boost of energy--the activation energy--and enzymes lower that.
Q:Chemistry GCSE what is a catalyst?
A catalyst is something that makes a chemical reaction happen faster. An example is when manganese oxide (MnO2) is added to hydrogen peroxide (H2O2), and the hydrogen peroxide starts to break up into water and oxygen. Catalysts are either of natural or synthetic origin. They are useful because they leave no residue in the solution they have sped up. A catalyst also can also be used in a reaction again and again. Catalysts work by lowering the activation energy of a reaction. This allows less energy to be used, thus speeding up the reaction. The opposite of a catalyst is an inhibitor, which slow down reactions
