put in a way that a freshman in high school can understand please =)
which of the following statement apply both to enzymes and to any other catalysts: their activity is stopped by high temperature. they speed up chemical reaction. they are proteins. they are not used up during the reaction
Is the catalyst in the chemical reaction better?
The efficiency of the catalyst is very high, as long as a little bit on it, with too much in addition to increase the cost of meaningless. Positive catalyst can increase the rate of several thousand times. Fast ... I know there will be about a thousand years shortened to 1 second. There are slowdown in the catalyst, people taught not learned. Other versions of the textbook is not clear. Should not learn.
When there is a catalyst in the chemical equation, it is not necessary to match the atoms of the catalyst
No, the catalyst is written above the equal sign, not the reactants, nor the product
Could God be Discribed as a Catalyst?
it is my understanding that a Catalyst will bring something together that is already created. God on the other hand, according to Judeo-Christian Theology, he didn't just bring it together, he created it. plus, if the Judeo-Christian God did exist, we would have to assume (because of archaeological and scientific evidence) that He is the God of the Bible and that he does play a role in the same of things.
High school knowledge __ teacher do not know right!
Nothing to do, but with the percentage of activated molecules, is proportional to
What kind of compounds or elements can be used as catalysts in high school chemistry? What is the catalyst for what?
Iron, manganese dioxide, mainly metal and its oxides.
What makes an enzyme a catalyst?
A catalyst is a substance that speeds up a chemical reaction, by lowering the activation energy, and which is not consumed or permanently altered in the process (such that after it has catalyzed the reaction once, it can catalyze the reaction again, and again -- multiple turnover). Catalysts can be as simple as a monatomic ion; they can also be inorganic compounds, non-biological organic molecules, or biological molecules. Biological catalysts are enzymes. Enzymes meet all of the criteria for being a catalyst (speed up chemical reactions, by reducing the activation energy, and are not permanently altered).
Does the catalyst slow down the chemical reaction rate? Still can only accelerate
As far as I know, depending on the definition of the catalyst to reduce the activation energy can only accelerate the reaction rate. However, some substances can reduce the rate of reaction, for example, to dilute the reaction solution to slow down the reaction rate, but slow down the general mention of the catalyst.
