It always depends on the catalyst!
But in general the most common disadvantages of catalysts are as follows:
- further (extensive/complex) purification to get rid of the catalyst
- costs for (expensive) catalysts
- environmental problems when the catalyst can't be (easily) regenerated producing problematic waste
Disadvantages:
Lowers the cost of production
Lowers the time of production
The work done by the catalyst is to change the mechanism of a reaction, actually the alternate way using the catalyst needs lesser energy to the same reaction without the catalyst.
A catalyst E.g. Using a porcelain catalyst, you can crack long chain hydrocarbons or using a nickel catalyst at 60 degrees, you can harden vegetable oil (hydrogenated)
An addition reaction, specifically it is called hydrogenation.
An inorganic catalyst can often catalyse many different reactions whilst most enzymes are reaction specific enzymes allow a reaction to take place which only forms pure products reducing the costs for separation techniques lower temperatures and pressures can be used than with inorganic catalysts inorganic catalyst can often be poisonous and cause disposal problems at the end of their industrial lives. Enzymes are biodegradable btw enzymes are living catalysts
The advantages of using an industrial water filters come in a wide spectrum of ways. From being able to be implemented in new or existing systems to taking care of the smallest flow of water in batches.

Jewelry, coins and also tests are being done on using gold as an industrial catalyst
It lowers activation energy requirements.
To increase the rate of catalpas reaction by using the same liver is simple. It is the biological catalyst that alters the rate of reaction that changes itself.

When activation energy is lowered (e.g. by using a catalyst) the reaction rate increases (at the same temperature)
No, HCl is a simple molecule while enzymes are complex organic molecules generally proteinic nature.

A catalyst actually decreases the activation energy of a reaction in 2 ways: 1) By a process called adsorption, it attracts the molecules of the reactants to its surface so that they are closer together and can react more easily by colliding more successfully. 2) It creates a transition state, which is an inter mediate state before the final reaction occurs, which creates an intermediate, unstable compound using the catalyst itself. By the time the final product is formed, a new product as well as the original catalysy are remaining and the activation energy is considerably reduced.
