What parameter involved in a chemical reaction will change with the addition of a catalyst?
The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.
What is positive catalyst?
A catalyst is a substance whose presence alters the rates of the reaction without themselves undergoing any permanent change in concentration or composition .
Breaking of a larger hydrocarbon molecule into a smaller one by heating in the presence of a catalyst is called?
Cracking , Cracking is the name given to breaking up large hydrocarbon molecules into smaller and more useful bits. This is achieved by using high pressures and temperatures without a catalyst, or lower temperatures and pressures in the presence of a catalyst.
What is the reaction of an alkene and water in the presence of an acid catalyst to produce an alcohol called?
hydration
How does the presence of a catalyst affect the enthalpy change of a reaction?
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
What presence of an speeds up a reaction?
catalyst
What affectts the speed of a chemical reaccion?
Temperature, concentration, presence of a catalyst.
What is Hydrogenated Tallow Acid?
"Hydrogenated Tallow AcidS" is a mixture of saturated fatty acids which are produced from animal fat by hydrolysis and then treated by hydrogen at high temerature and pressure in a presence of special catalists.
How do you make ethanol?
simply hydrate an alkene, that is addind water to it with the presence of a catalyst

What factor will most likely lower the activation energy of a reaction?
The presence of a catalyst will lower a reaction's activation energy.
How do manufactrers make trans fat?
The bubble hydrogen gas through oil in the presence of a catalyst.
Why chlorophyll acts as a catalyst in photosynthesis?
Chlorophyll is NOT really a catalyst. The presence of chlorophyll in the absence of light does not catalyze photosynthesis. Chlorophyll plays a part in photosynthesis, it captures light energy.
