How does temperature affect chemical reactions?

Temperature plays a crucial role in chemical reactions. Generally, increasing the temperature increases the reaction rate.

Why does a higher temperature speed up reactions?

Higher temperatures provide more energy to the molecules, causing them to move faster and collide more frequently, which increases the chances of reactions.

Are there any reactions that slow down with increased temperature?

Yes, some reactions, like certain exothermic reactions, can slow down at higher temperatures due to changes in equilibrium.

Can you give an example of a reaction that is affected by temperature?

Sure! The decomposition of hydrogen peroxide is an example; it speeds up at higher temperatures.
