Provided the catalyst is appropriate for the reaction, it will accelerate the reaction. In other words, the reaction will reach equilibrium between reactants and products faster than it would otherwise have done. The catalyst is unchanged, i.e. at the end of the reaction it is in the same chemical state that it was in at the start.
In living systems, the catalysts are made by cells and are called enzymes.

Which would increases the reaction rate?
Temperature
What does a catalyst reduce to a chemical reaction?
Adding a catalyst a chemical reaction can occur with a lower activation energy.
What can reduce the amount of energy needed for a chemical reaction to take place?
adding a catalyst to the reaction
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
What it will change adding a catalyst to a chemical reaction?
It will increase or decrease the speed of the chemical reaction.
Which would increases the reaction rate?
Temperature
How would the equilibrium concentration of H2O be affected by adding a catalyst to the mixture?
None. A catalyst affects only the rate of reaction, and if the reaction is already at equilibrium, the net rate of the reaction is zero and remains so after a catalyst is added.
What does a catalyst reduce to a chemical reaction?
Adding a catalyst a chemical reaction can occur with a lower activation energy.

What it will change adding a catalyst to a chemical reaction?
It will increase or decrease the speed of the chemical reaction.
How do catalyst and inhibtors affect reaction rate?
A catalyst speeds up the reaction and lowers the amount of heat needed.
The reaction rate of melting ice can be increased by what 1 adding catalyst 2 increasing concentration of the reactant 3 increasing pressure on the reaction 4 none its physical?
adding a catalyst none its physical
How does the additions of a catalyst affect the energy of activation of a chemical reaction?
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
How does a catalyst affect the speed of a reaction?
A catalyst enables more particles to reach the activation energy and to take part in the reaction. Therefore the speed of the reaction increases.
How does the presence of a catalyst affect the enthalpy change of a reaction?
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
How does the present of a catalyst affect the rate of reactions?
A catalyst is a substance which speeds up the rate of reaction. After the reaction it remain chemically unchanged. It does NOT affect the position of equilibrium. There can also be negative or "poisoned" catalysts as in Rosenmunds reaction.
