Best practice
Always ensure the verb "increase" agrees in number with the subject "temperature". Use "increases" when referring to a singular temperature. Correct usage: As temperature increases, reaction rate rises.
Common error
A common mistake is to use the base form of the verb "increase" after "temperature". Remember that "temperature" is singular, so the correct form is "increases". For example, avoid writing "As temperature increase", and instead use "As temperature increases".
