the speed of the chemical reaction can be increase or decrease by using Dash
Answers
Hello... ✌
Answer:
There are four main factors that can affect the reaction rate of a chemical reaction:
Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction...
Physical state of the reactants and surface area...
Temperature…
Presence of a catalyst...
To increase the speed of the chemical reaction
Temperature. increase temperature = more collision.
surface area. increase surface are = more collision.
concentration. higher concentration = more collision.
catalysts. lowers amount of energy needed for reaction.
nature of reactants. some substances are more reactive than others.
How can we speed up or slow down a reaction?
1) The rate of a chemical reaction can be speeded up or slowed down by changing the temperature...
2) Other ways of changing the rate of the Chemical Reactions are, by stirring them and/or changing the size or concentration of the reactants.
