Question

What is the term used for partially deactivated palladised charcoal?

Answer 1

We have to remember that the catalyst is nothing but the one of the substances in the chemical reaction. It is the reason for altering the rate of the chemical reaction, but it is not involving the chemical reaction. The action of catalysis is popularly known as catalysis. These catalysis are classified as many types. One of the classification of catalysis is based on the catalysis, it impacts the rate of the chemical reaction. There are positive catalysis and negative catalysis. The positive catalysis is nothing but it increases the rate of the chemical reaction by the presence of these catalysts. The negative catalysis is nothing but it decreases the rate of the chemical reaction by the presence of these catalysts. One of the classification of catalysis is based on the phase of catalysis, it impacts the rate of the chemical reaction. There are homogeneous catalysis and Heterogeneous catalysis. The homogeneous catalysis is nothing but reactant, product and catalyst are in the same phase. The heterogeneous catalysis is nothing but reactant, product and catalyst are in different phases.

Complete answer:
Lindlar’s catalyst is the term used for partially deactivated palladised charcoal.
Lindlar’s catalysts are an example of heterogeneous catalysis.
Lindlar’s catalysts are used for the reduction of alkene to alkane.
Lindlar’s catalysts are made up of palladium and calcium carbonate.
According to the above discussion, we conclude Lindlar’s catalyst is the term used for partially deactivated palladised charcoal.

Note:
We need to know that in the reaction three things are main. There are reactant, product and reaction conditions. The reactants are always on the left side of the equation. If more than one reactant in the equation means by using plus sign. The products are always on the right side of the reaction. Something here also follows. More than one product by using plus sign. In between reactant products are used arrows to find the reaction direction in the equation.
