What is the slowing down of neutrons to increase the probability of their absorption by atoms in uranium called?
neutron moderation
how to decrease margin of error in probability sampling?
With probability sampling you have no control over the units that are sampled. So the only way to reduce the margin of error is to increase the size of the sample.
What relationship exists between an enzyme and a catalysm?
Enzymes catalyze biochemical reaction in organisms by lowering the activation energy to begin a reaction, which, of course, requires some energy input.
Is the probability 1.2 nil possible?
Probabilities go from 0 to 1. This is a steady increase with 0.5 meaning 50% of "equally likely to happen as not." 0 probability means that it is impossible something will happen. 1 probability means it is definite something will happen. Therefore, you cannot have probability 1.2 as this is more than "definitely going to happen."
Why is the spread of an equity CDO tranche decreasing with correlation?
When you increase correlation, you are increasing the probability of having very large losses, as well as the probability of having no loss at all. So, you are increasing the probability that senior tranches might experience significant losses but also the probability that the equity tranche is left untouched. As a consequance the spread on the latter decreases.
IS it true that enzymes increase the number of collisions in a chemical reaction?
No that is false. Enzymes do NOT increase number of collisions in a chemical reaction.
What are enzymes considered?
Enzymes are considered to be catalysts; they increase the rate of a chemical reaction.
What is the effect of increasing the concentration of enzymes in a reaction?
If the reaction speed has not already peaked, then it will increase
Enzymes are catalysts. How do enzymes increase the reaction rate?
Enzymes are natural catalysts, these natural catalysts speed up reactions.
Do Enzymes increase or decrease the Activation Energy of a Chemical Reaction?
decrease
Which best describes the role of enzymes in chemical reactions?
to increase the reaction rate
Do enzymes lower or increase the need for energy in chemical reaction?
In some cases.
Do enzymes slow down or speed up a chemical reaction?
No, the sole purpose of enzymes are to increase the rate of a chemical reaction. Even if they are not at an optimal temperature, they will not slow down the reaction. They won't work as efficiently, but it will still be slightly faster than without the enzymes.
How are enzymes represented in a chemical equation?
Enzymes are catalysts and increase the speed of a chemical reaction without themselves .A chemical reaction can be represented by a chemical equation. An enzyme is a protein that speeds up a biochemical reaction .
What affect rates does a enzyme catalyzed reaction have?
Enzymes increase the rate of reaction by changing the reaction mechanism to one with a lower activation energy.
What aspects of chemical reaction are enzymes known to affect?
Enzymes affect the speed of reactions predominantly. In some instances in which more than one reaction is possible, enzymes increase the speed of the normally slower reaction enough to make it predominate, while the other possible reaction is effectively suppressed.
Why does increased temperature speed up a reaction?
The motion of chemical entities increase with the temperature and the probability of collisions also increase.
