When a catalyst is removed from a chemical reaction, the reaction will proceed at a slower rate. This is because the catalyst helps lower the activation energy required for the reaction to occur. Without the catalyst, more energy is needed for the reaction to take place, resulting in a slower reaction process.
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.
None: The catalyst remains unchanged, but the catalyst also speeds up the reaction.
Catalyst is the substance that speeds up a chemical reaction without being consumed in the process.
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
A substance that accelerates a chemical reaction is called a catalyst. Catalysts work by lowering the activation energy needed for a reaction to occur, which speeds up the reaction without being consumed in the process.
A substance that speeds up the rate of a chemical reaction without being consumed in the process is called a catalyst. Catalysts provide an alternative pathway with lower activation energy for the reaction to occur, increasing the reaction rate without being altered themselves.
A substance that speeds up a chemical reaction without being consumed is called a catalyst. Catalysts lower the activation energy needed for a reaction to occur, allowing it to proceed faster, but they remain unchanged at the end of the reaction.
A substance that speeds up a chemical reaction without undergoing a permanent change itself is called a catalyst. Catalysts work by providing an alternative pathway for the reaction to occur, thereby lowering the activation energy needed for the reaction to proceed. Once the reaction is complete, the catalyst remains unchanged and available to facilitate more reactions.
Adding a catalyst to a chemical reaction can increase the rate of the reaction by providing an alternative pathway with lower activation energy. This allows the reaction to occur more quickly without being consumed in the process. Essentially, a catalyst speeds up the reaction without being permanently changed itself.
A catalyst doesn't undergo a chemical change during a chemical reaction.
