Effect of Temperature

Definition:

• Temperature refers to the measure of the average kinetic energy (movement) of particles in a substance.

Importance:

• Temperature has a significant impact on the rate of chemical reactions.

Increased Temperature:

• When temperature increases, particles gain more energy, and they move faster.

Effect on Reaction Rate:

• Faster Reactions: Raising the temperature results in a higher rate of reaction.
  • Faster-moving particles collide more frequently.
  • Example: Food cooking faster at higher temperatures.
• Energy and Activation: Higher temperature provides more energy to overcome activation energy barriers, making reactions more likely to occur.

Applications:

• Baking: Cakes rise faster at higher oven temperatures.
• Chemistry labs: Controlling reaction rates by adjusting temperatures.
• Fuel combustion: Engines burn fuel more efficiently at higher temperatures.
