Rate of reation is the time taken for a reaction to take place and the smell it has
NO! It is the rate of reactions!
When the number of particle collisions increase the rate of chemical reactions also increase.
exploding dynamite
No, they Increase the speed of chemical reactions
5 factors that can affect the rate of chemical reactions are temperature, pressure, concentration, stirring, catalysts.
Generally at high temperature the rate of chemical reactions is greater.
increasing the concentration increases the rate of the reaction
The rate of most will also increase.

Enzymes serve to speed up reactions by lowering the energy of activation
Enzymes are special proteins that speed up the rate of condensation and hydrolysis reactions by lowering the activation energy required for these reactions to occur. They act as biological catalysts to facilitate these biochemical reactions in living organisms.
