Questions & Step-by-Step Solutions

What happens to the reaction rate if the temperature is increased by 20°C for most reactions?
  • Step 1: Understand that temperature affects how fast reactions happen.
  • Step 2: Know that for many chemical reactions, increasing the temperature by 10°C can double the speed of the reaction.
  • Step 3: If you increase the temperature by 20°C, that is two times the 10°C increase.
  • Step 4: Since each 10°C increase can double the reaction rate, a 20°C increase means the reaction rate will double twice.
  • Step 5: Therefore, the reaction rate typically increases by a factor of four when the temperature is raised by 20°C.
