In a reaction for every rise of temperature, the rate is tripled. If the temperature is increased from to , the rate of the reaction will become
View answer and explanation
Correct option: A
81 times
Option A (81 times) is correct because the rate increases by a factor of 3 for every 10°C rise, and the temperature increases by 40°C.
