a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
catalyst decreases the activation energy of a chemical reaction, thereby increasing the rate of the chemical reaction
A catalyst speeds up the rate of a reaction.
None: The catalyst remains unchanged, but the catalyst also speeds up the reaction.
s
A catalyst increases the reverse rate of the reaction
A catalyst would lead to the reaction being quicker.
By making the pellets porous, you maximize the surface to volume ratio of the catalyst, which allows you to use less of it, but get the same effect.
A catalyst speeds up the rate of a reaction.
A catalyst alters the rate of a chemical reaction.
A catalyst speeds up the rate of a reaction.
None: The catalyst remains unchanged, but the catalyst also speeds up the reaction.
A catalyst lowers the activation energy of a reaction.
The correct answer is a simple one: The system is unaffected by a catalyst in a system in equilibrium.
s
A catalyst increases the reverse rate of the reaction
A catalyst would lead to the reaction being quicker.
A properly chosen, specific catalyst is able to speed up the rate of a particular chemical reaction
By making the pellets porous, you maximize the surface to volume ratio of the catalyst, which allows you to use less of it, but get the same effect.
To Cause a Chemical reaction. A properly chosen, specific catalyst is able to speed up the rate of a particular chemical reaction.
