Catalysts affect reaction rates by providing an alternate route of reaction with lower activation energy. Therefore, they speed up the process they are catalyzing in both the forward and reverse directions.
catalyst increases the rate of the reaction
With a catalyst the reaction rate is higher.
a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
Temperature
A catalyst speeds up the rate of reaction, and lower the activation energy needed.
A catalyst is a substance that speeds up the rate of a chemical reaction without changing the substance. It does this by reducing the minimal reaction energy. A catalyst is not used up in a reaction therefore they last indefinitely.

A catalyst speeds up the rate of a reaction.
A catalyst speeds up the rate of a reaction.
Temperature
A catalyst speeds up the rate of reaction, and lower the activation energy needed.
The catalyst is a substance added to the reaction to speed it up. All in all, thecatalystlowers the reaction rate.
The catalyst is not a reactant; a catalyst only favors a chemical reaction, the reaction rate and yield.
A catalyst is a substance that speeds up the rate of a chemical reaction without changing the substance. It does this by reducing the minimal reaction energy. A catalyst is not used up in a reaction therefore they last indefinitely.
There are positive catalysts used when the reaction rate is needed to be faster or the negative catalysts to make the reaction rate slower.
Temperature
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.
