A catalyst is a substance which speeds up the rate of reaction. After the reaction it remain chemically unchanged. It does NOT affect the position of equilibrium. There can also be negative or "poisoned" catalysts as in Rosenmunds reaction.

How does a catalyst affect the rate of an industrial reaction?
Catalysts speed up reactions by reducing the activation energy.
Substance that increases rate of chemical reactions?
catalyst
Effect of catalyst on the rate of reverse step?
A catalyst increases the reverse rate of the reaction
What factors affect chemical reaction and how?
Assuming you mean rate of reaction. The factors are particle size, concentration, temperature and catalyst. The smaller the particle size the bigger the surface area exposed, so more particles are available for reactions to occur. The higher the concentration the more particles present so more reactions take place. The higher the temperature the faster the particles move around so there are more frequent reactions between particles. Having a catalyst present speeds up a reaction without the catalyst being used up.
What is the biological catalyst that speed up the rate of chemical is?
An enzyme is the biological catalyst that speeds up chemical reactions.
What are the four factors that affect the rate of a chemical reaction?
Whether a catalyst is present or not, Concentrations of reactants, Temperature, Pressure (but this is least likely to affect rate)
How does a catalyst affect the rate of an industrial reaction?
Catalysts speed up reactions by reducing the activation energy.
What is a catalyst and why is it important in certain reactions?
a catalyst speeds up the rate of reaction

How would reactions be affected if enzymes were not present in cell?
enzymes are the catalyst that aid the reactions taking place inside our bodies. if there were no enzymes, our metabolic processes would slow down to such a rate that we would not be able to survive.
What factors affect the rate of catalase catalyzed reactions?
If your question is "What affects catalyst performance?" (i.e. what stops them from working) then there are 2 main things: Atoms permanently bonded to the surface, blocking it, and so that stops other reactant molecules from sticking to it (catalyst poisoning) Catalyst sintering: This can be seen on high temperature solid metal catalysts, where there is a gradual loss of surface area for reactant molecules to stick to as a result of the individual catalyst surface atoms combining together (due to the heat) to make one big blob of lower surface area
How do catalyst and inhibtors affect reaction rate?
A catalyst speeds up the reaction and lowers the amount of heat needed.
What are the 5 factors that can affect the rate of chemical reactions?
5 factors that can affect the rate of chemical reactions are temperature, pressure, concentration, stirring, catalysts.
