Does a increase in pressure cause an increase of reaction rate?
Yes
Do catalyst increase equilibrium constant?
No they do not. A catalyst is a thing (atom, molecule, element, etc.) that speeds up a chem. rxn by lowering the activation energy without being altered itself. So it only cause the reaction to occur faster, but will not have any affect on the equilibrium. Also, since the catalyst is not altered, it should 'come out' exactly as it 'went in.'
Why is an enzyme considered a catalyst?
An enzyme is referred to as a catalyst as it sets off the digestive process beginning with amylase in the mouth which is produced by the salivary glands (...and followed by all the other enzymes that are mixed with the food along the alimentary canal)
What will cause the reaction time of a reflex to increase?
a large number of neurons-therefore, synapses-involved
In the reaction 2SO2 plus O2 Reversible 2SO3 which change would cause the greatest increase in the concentration of SO3?
Increase the concentration of SO2
What are two variables that would cause a chemical reaction to have a fast reaction rate?
Increased concentration, increased temperature, and a catalyst will all increase reaction rates relative to what they normally are. Some reactions however will still be slow even with the change in these variables.
What is the effect of a catalyst on a chemical reaction?
To Cause a Chemical reaction. A properly chosen, specific catalyst is able to speed up the rate of a particular chemical reaction.

How does a catalyst change the rate of a chemical reaction?
Lowers the activation energy of a reaction, therefore speeding the reaction up.Catalysts speed up chemical reactions. They do not change the products or reactants of the reaction, and are not used up or consumed in the reaction. Biological catalysts are called enzymes. Catalysts lower the activation energy (or energy needed to start a reaction), and cause the reaction to occur more quickly.
An increase in temperature will cause the rate of a chemical reaction to?
Increasing the temperature the dissolving rate increase.
Which methods will usually cause a reaction to speed up?
Combining the reactants at a lower temperature. Reducing the concentration of reactants. Grinding one of the reactants into a powder. Removing the catalyst.

How does temperature increase cause the rate of a reaction to increase?
It increases the kinetic energy of the molecules (APEX)
How does temperature affects the order of a reaction?
as temperature increase the rate of the reaction increase because ther is an increase in the kinetic energy causeing the molecules to move more rapidly cause a increase in collision.
What does a temperature increase cause the rate of a reaction to increase?
As temperature increase the speed and energy of molecules increase and the collisions are more probable.
What a does a temperature increase cause the rate of a reaction to increase?
As temperature increase the speed and energy of molecules increase and the collisions are more probable.
