What effect does a catalyst have on a system equilibrium?
The correct answer is a simple one: The system is unaffected by a catalyst in a system in equilibrium.
What effects do catalysts have on an equilibrium system?
They catalyse both the forward and reverse reactions, so the position of equilibrium is unaffected. The system will however reach equilibrium more quickly.
Why is radioactivity of an element unaffected by the usual factors that affect the rate of chemical reactions such as ordinary changes of temperature and condcentration?
because it is radiation and radiation can not be affected by temperature and/or concentration.
Does an increase in pressure at constant temperature increase the rate constant of a reversible reaction in both directions?
The rate constant is unaffected, as demonstrated by Arrhenius equation: k = Ae^(-E/RT) where A is the pre-exponential factor (constant for a particular reaction) E is the activation energy R is the molar gas constant T is the thermodynamic temperature However, when pressure is increased at constant temperature for a gaseous reversible reaction, the concentrations of every reactant and product increase by the SAME factor. Since Kp (pressure equilibrium constant) is to remain constant, it means that the position of equilibrium will shift in such a way so as to decrease the total number of moles of gaseous species. Note: This answer can be improved by proving the last statement using a general example which, due to lack of time, I skipped. (Although some people might get the logic!!!)
Is magnetism unaffected by paper glass or plastic?
true it is unaffected
Why temperature increases dencity decreases?
Density is mass divided by volume. For most substances, when the temperature increases the volume will increase (assuming constant pressure), but the mass will of course remain unaffected.
What effect does a promoter catalyst have on the position of the equilibrium?
By definition a catalyst cannot affect equilibrium because although a catalyst can speed up a chemical reaction, it cannot change the thermodynamics of it, and equilibrium is determined solely by thermodynamics. A catalyst may help a system reach equilibrium more quickly, but it will not change it. One possible way a catalyst could affect equilibrium is by introducing a catalyst that affects a different reaction involving the substrate or products of the original reaction, but this would be cheating since the system would no longer be closed.
When was Apparently Unaffected created?

How do you use unaffected in a sentence?
Because she is independently wealthy, she is unaffected by the weak economy or the price of gasoline.
How can a country can be unaffected by world's events?
If the media of the country ignores foreign news, then the country will be unaffected.
When gold jewelry is unaffected by perspiration chemical or physical?
when gold jewelry is unaffected by perspiration it is a physical property.
What is the prefix affected?
unaffected
