How do catalysts affect energy diagrams?
Energy diagrams are useful to illustrate the effect of a catalyst on reaction rates. Catalysts decrease the activation energy required for a reaction to proceed (shown by the smaller magnitude of the activation energy on the energy diagram in Figure 7.14), and therefore increase the reaction rate.
How do catalysts work?
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the reaction. A catalyst works by providing a different pathway for the reaction, one that has a lower activation energy than the uncatalyzed pathway.
What is a real life example of a catalyst?
The definition of a catalyst is someone or something that speeds up or brings about an event. An example of catalyst is how President Bush’s claims that Iraq had weapons of mass destruction started the war in Iraq.
What are the main features of catalyst?
The following are the general characteristics of a catalyst: (i) A catalyst remains unchanged at the end of the reaction. The amount and the chemical composition of a catalyst remain unchanged in a catalytic reaction. However, the catalyst may undergo a physical change.
What are advantages of using a catalyst?
Advantages. Catalysts speed up the rate of reactio , which saves money because the plant doesn’t have to operate for as long to produce the same amount of product. Catalysts allow the reaction to work at a much lower temperature. This reduces the energy used up in a reaction which is good for sustainable development. They save industries money.
What are the types of catalysts?
Catalysts can be divided into two main types – heterogeneous and homogeneous. In a heterogeneous reaction, the catalyst is in a different phase from the reactants. In a homogeneous reaction, the catalyst is in the same phase as the reactants.
