Step-by-step explanation:
To increase the rate of a reaction it is required to provide the following conditions:
- Increase the concentration of solute in solution
- Increase surface area of solute particles
Therefore, when we increase the concentration of reactant molecules then there will be more number of solute particles available to collide with solvent particles. Hence there will be increase in rate of reaction.
Thus, we can conclude that a chemical reaction be speed up by pack in more of the reactant to increase the concentration.
