What is the rate of Chemical reaction'

What is the rate of the Chemical Reaction?
  • The rate of a reaction is a measure of how quickly reactants change into products.
  • An increase in temperature, generally increases the rate of the reaction.
  • A catalyst is a substance that speed up the reaction without itself being used up.


 
Questions:
  1. Define the rate of the reaction.
  2. Define the catalyst.
  3. Does temperature play a role in chemical reactions? Justify.

    2. 3. Yes, the temperature plays a role in chemical reactions because as temperature increase, the rate of the reaction increase since temperature is considered a catalyst.

    3. 1- Change in the concentration of a reactant or product per unit time.

    4. 1- The rate of a chemical reaction depends on its reaction mechanism. It's the speed at which a reaction takes place.
