What else can I help you with?
Why can a catalyst speed up a reaction even at low temperature?
Because catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction increases.
What does it means if an enzyme is a catalyst?
Enzyme will reduce the activation energy of the reaction, thereby the speed of the reaction increases or acting as a catalyst.
Why does a catalyst speed up the rate of reaction?
The use of a catalyst increases the chance of particles meeting. This causes there to be a decrease in activation energy, and results in an increase in rate of 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 .
What are the 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.
Why can a catalyst speed up a reaction even at low temperature?
Because catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction increases.
How does a catalyst affect the speed of a reaction?
A catalyst enables more particles to reach the activation energy and to take part in the reaction. Therefore the speed of the reaction increases.
What does it means if an enzyme is a catalyst?
Enzyme will reduce the activation energy of the reaction, thereby the speed of the reaction increases or acting as a catalyst.
Why does the rate of a reaction speed up?
Catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction (or the rate of the reaction) increases.
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.
Why does a catalyst speed up the rate of reaction?
The use of a catalyst increases the chance of particles meeting. This causes there to be a decrease in activation energy, and results in an increase in rate of reaction.
A material used to increase the rate of a reaction is a...?
catalyst. A catalyst is a substance that increases the speed of a chemical reaction without being consumed in the process.

A catalyst increases the rate of a chemical reaction by changing which of the following conditions?
A catalyst can speed up the rate of a given chemical reaction by lowering the activation energy required for the reaction to occur. However, the catalyst does not change the total free energy from reactants to products.
What it will change adding a catalyst to a chemical reaction?
Adding a catalyst to a chemical reaction can increase the rate of the reaction by providing an alternative pathway with lower activation energy. This allows the reaction to occur more quickly without being consumed in the process. Essentially, a catalyst speeds up the reaction without being permanently changed itself.
