Catalysts speed up chemical reactions by?

Answer 1

Catalysts are very effective and economical in industrial area. Catalysts increase the rate of a reaction by reducing the activation energy of the reaction. activation energy is the overall energy needed for a reaction to initiate. Both reactions such as exothermic or endothermic has activation energy, so we need to overcome the activation energy for the reaction to proceed. Actually the way it works is quiet simple, it absorbs the reactant particles on its surface reducing their bond energy. When the energy between bonds is weaker, its easier for reactant particle to change to products. Activation energy comes from when reactant particles collide with each other with high kinetic energy.

Answer 2

It either lowers the activation energy or increases the activation energy, allowing the reaction to occur faster or slower respectively. It modifies the rate of the reaction.

Answer 3

A catalyst increases the rate of a chemical reaction without being consumed or changed by that reaction. It does this by reducing the amount of energy required to activate the reaction.

Answer 4

they do that buy helping the chemical reaction

Answer 5

Becoming part of the product after the reactions occur

Answer 6

providing an alternative pathway with lower activation energy, allowing the reaction to occur at a faster rate. Catalysts do not get consumed during the reaction and can be reused multiple times.

Answer 7

Enzymes
