What are two ways the speed of a chemical reaction can be increased if both of the reactants are aqueous solutions?
It can be done with those substance which remains as it was before the reaction but increases the speed of the reaction.
Why is the rate of a chemical reaction likely to speed up if the temperature increases?
See details about the Arrhenius reaction at the link below.
The role of a catalyst?
A catalyst is a substance which alters the rate of a chemical reaction but is chemically unchanged at the end of the reaction. basically it increases or decreases the speed of a chemical or biological reaction, but it does not get itself involved in the reaction. hoped this helped (:
What does a catalyst do in a chemical reaction?
Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.
What happenes to the speed of a chemical reaction when a catalyst is present?
The speed of a chemical reaction may increase or decrease by the addition of a catalyst. In the synthesis of ammonia by Haber's process , Fe + Mo mixture acts as a catalyst which increases the formation of ammonia,here Fe + Mo mixture is positive catalyst(increases the speed of the reaction). The oxidation of chloroform (CHCl3) by air in presence of sunlight is retorted by the edition of 1% ethyl alcohol in to it. Here alcohol acts as a negative catalyst (decreases the speed of the reaction)to the oxidation of chloroform .
How does increasing the temperature effect a chemical reaction?
Raising the temperature makes chemical reactions faster.
As the temperature of a chemical reaction in the gas phase is increased the rate of the reaction increases because?
Increasing the temperature generally increases the speed with which molecules move.
How does pressure speed up a chemical reaction?
Increasing the pressure on a reaction involving reacting gases increases the rate of reaction. Changing the pressure on a reaction which involves solids or liquids has no effect on the rate of reaction.
Do enzymes speed up a chemical reactions?
Ensymes speed up a chemical reaction by acting as organic catalyst, a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
During the chemical reaction starch is broken down into glucose What will most likely happen if the biochemist adds an enzyme to the reactants?
the reaction will speed up
What are two ways the speed of a chemical reaction can be increased if both of the reactants are aqueous solutions?
It can be done with those substance which remains as it was before the reaction but increases the speed of the reaction.
How is heat involved in chemical changes?
Heat increases the speed at which the molecules move, thus increasing the speed of the reaction.
Why is the rate of a chemical reaction likely to speed up if the temperature increases?
See details about the Arrhenius reaction at the link below.

Does the change of temperature will slow or faster the chemical reaction?
No, an increase in temperature will speed up the reaction. This is because the heat energy is transferred into kinetic energy (movement energy) in the reactors and this increases their speed and so increases the rate at which they collide with each other, increasing the rate of the chemical reaction.
What are the salient features of catalyst?
A catalyst alters (usually increases) the speed of a chemical reaction in which there is no net change in the amount of catalyst present after reaction is complete.
What can speed up a chemical reaction by decreasing?
chemical reaction
