Explanation:

Hope this answer will help you.

Answer 2

• Adding heat to a reaction will increase the rate if the reaction is endothermic.
• Removing heat from an endothermic reaction will decrease the rate but rate will increase in case of endothermic reaction.
• Adding a positive catalyst always increases the rate of a reaction.
• Diluting the solution involved in the reaction will decrease the rate of the reaction.
• Removing an enzyme from an enzymatic reaction will drastically decrease it's rate.
• Lowering the temperature of a reaction will decrease the rate of the reaction.
• Increasing the temperature of a reaction will normally increase the rate of the reaction.
• Decreasing the surface area of the reacting species will decrease the rate of reaction.
• Increasing the concentration of a solution in the reaction increases the rate of reaction.
• The minimum amount of energy needed to start a reaction us known as activation energy.
