### Catalysis

What is catalysis?

### Re: Catalysis

Catalysis is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst and are purely mechanisms that lower activation energy and are not included in the equation, therefore, they will not be in the rate law

### Re: Catalysis

It is basically the process of speeding up a reaction by providing a new pathway and lowering the activation energy.

### Re: Catalysis

Catalysis results in lowering the activation energy for a reaction to proceed, thus increasing the rate constant.

### Re: Catalysis

Can someone help explain the gas phase example of Nitric Oxide that Lavelle gave for Homogeneous Catalyst? I don't quite get how we get to 3/2 O2?

### Re: Catalysis

Also, do catalysts affect the reverse reaction in the same way that it affects the forward reaction?

### Re: Catalysis

catalysis decreases activation energy of a reaction

### Re: Catalysis

does anyone know if catalysis applies to the reverse reaction as well? Like, would a catalyst also affect how quickly products can form back into reactants

### Re: Catalysis

A catalyst is a reactant in the first step, and a product in the second step. It lowers activation energy, and speeds up a reaction.

### Re: Catalysis

Catalysis is when the rate of a reaction is increased by decreasing the necessary activation energy of a reaction through the use of a catalyst such as an enzyme.
