Why biological catalysts remarkable compare with industrial catalysts?
Biological catalysts are remarkable because they help the body to perform its daily functions that keep humans and animals alive and working properly. Industrial catalysts are used in the chemical industry to increase outputs and make products run more smoothly.
Why is an example of a heterogeneous catalyst?
catalysts which are in the same phase to that of reactants and products
Why are all enzymes are catalysts but not all catalysts are enzymes?
but all catalysts aren't enzymes...
Difference between homogeneous and heterogeneous catalysis?
Homogeneous catalysis is used over heterogeneous for the following reasons 1)There are more complicated catalytical sites (chemically and geometrically) which gives improved selectivity to a certain product 2) The catalysts are usually in solution and so access to the reagents is easier so there is improved activity and milder reaction conditions can be used. 3) Another advantage of the catalysts being in solution is that the heat transfer for highly exothermic or endothermic reactions is not a problem 4)Mechanisms are better understood. Advantage of heterogeneous catalysis is that the catalyst is usually solid and therefore is easier to extract and recycle.
Are Noble gases catalysts?
No. Generally they are not catalysts
What type of catalysts are platinum CFCs and magnesium under these conditions?
Platinum: heterogeneous CFC: homogeneous Mg: heterogeneous
What are the examples of heterogeneous and homogeneous?
catalysts which are in the same phase to that of reactants and products
What are some of the heterogeneous mixture found in the industry?
what are some heterogeneous mixtures found in the industry
Is lead metal homogeneous mixture or heterogeneous mixture?
Lead is a chemical element, not a mixture.
What is the difference between heterogeneous catalysis and enzyme catalysis?
strictly speaking soluble enzymes are homogeneous catalysts and membrane-bound enzymes are heterogeneous.
What are the important classes of catalysts including both the inorganic and biological catalysts?
Catalysts are generally divided into homogeneous and heterogeneous ones. Homogeneous catalysts are in the same phase as the reactants, for instance a mineral acid is added to an aqueous solution of an ester to speed up hydrolysis. Heterogeneous catalysts are in a different phase to the reactants, for instance exhaust gases from a car engine pass over the heated metals of the catalytic converter to speed up their conversion to safer gases. Natural catalysts are called enzymes and are homogeneous.

How do you write a sentence that uses 'catalyst' as noun?
Enzymes function as cell catalysts.
Why is an example of a heterogeneous catalyst?
catalysts which are in the same phase to that of reactants and products
Industrial process which uses a catalyst?
Catalysts increase the speed of a reaction without taking place in the reaction themselves. This is very useful in industry as it means that chemicals can be made much faster through usually slow chemical reactions, and as the catalysts don't take part in the reaction themselves, they can be reused as much as its needed. Examples of catalysts in industries include the use of the biological catalysts enzymes to brake down substrates in baby foods into smaller simpler molecules. Catalysts lower the activation energy required for a reaction to occur. This will mean that more molecules will have the energy to react. Catalysts allow equilibrium to be established quicker. Catalysts in general lower reaction temperatures leading to lower production costs. Catalysts add to cost e.g. palladium in catalytic converters. Catalysts can be poisoned by waste products eg. Sulphur in petrol and oil can reduce the properties of catalytic converters.
