Question: What happens to the reaction rate if the temperature is increased by 20°C for most reactions?

Options:

Correct Answer: Rate doubles

Solution:

For many reactions, an increase of 10°C can double the reaction rate, so a 20°C increase typically results in the rate doubling.

What happens to the reaction rate if the temperature is increased by 20°C for most reactions?

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.

Temperature and Reaction Rate – The relationship between temperature and the speed of chemical reactions, often described by the rule that a 10°C increase can double the reaction rate.
