So it takes an 'easier' start, but the 'goal' is the same products.

What do catalyst substances do to the rate of a chemical reaction?
increase
What is the substances that increase the rate of a chemical reaction?
positive catalyst
What will change when a catalyst is added to a chemical reaction?
A catalyst speeds up the rate of reaction, and lower the activation energy needed.
Increase the rate of a chemical reaction without becoming part of the product?
catalyst
What causes an increase in the rate of a chemical reaction between 2 liquids?
Increasing the temperature will increase the reaction rate, as will finding a suitable catalyst.
What is a substance that speeds up the rate of a chemical reation?
catalyst

Increase the rate of a chemical reaction without becoming part of the product?
catalyst
Which of these would be expected to increase the rate of sa chemical reaction?
an enzyme or other catalyst
What causes an increase in the rate of a chemical reaction between 2 liquids?
Increasing the temperature will increase the reaction rate, as will finding a suitable catalyst.
The primary function of an enzyme or any biological catalyst is to?
Enzymes speed up the rate of chemical reactions by lowering activation energy, and are not used up in the reaction.
How is a catalysts different from a reactant?
a catalyst can affect the rate of a reaction. speeding it up.
What effect does a catalyst have?
a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
Why are chemical reactions that have equilibrium points close to completion preferable for manufacturing?
ans 1=when the rate of reverse reation become equals to rate of forward reaction,such chemical reation is in equilibrium
What is the difference between reagent and catalyst?
catalysts accelerate the rate of reaction but does not get consume in reaction, and reappear after reaction is over, whereas reagents initiate reation and get consume in reation.
