Yes, by lowering activation energy, Ea.
they speed up a reaction
A catalyst
Because catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction increases.
A catalyst can speed up a chemical reaction.
No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.
The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.
A catalyst.A catalyst.
A catalyst is a substance that initiates or accelerates a reaction. The catalyst will vary depending on the reaction so it is not possible to give a definitive answer to the question.
A catalyst functions to speed up a chemical reaction without being used up in the reaction, meaning that a catalyst can be used more than once.
The catalyst is a substance added to the reaction to speed it up. All in all, thecatalystlowers the reaction rate.
Catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction (or the rate of the reaction) increases.
A catalyst is a substance that speeds up a chemical reaction by providing an alternative reaction pathway with lower activation energy. The catalyst itself is not consumed in the reaction and remains unchanged at the end.
