Each increase of 10 degrees Celsius the reaction speed rises to 3 times that. The time it takes to react at a temperature of 25 degrees Celsius is 9 minutes. Determine the time needed at a temperature of 55 degrees Celsius.
From the information given, we know that for every increase of 10 degrees Celsius, the reaction speed triples. This means that the reaction rate at 55 degrees Celsius is 3^3 = 27 times faster than at 25 degrees Celsius.
Let's assume that the time it takes to react at 55 degrees Celsius is t minutes. Using the information given, we can set up a proportion:
time at 25 degrees Celsius / time at 55 degrees Celsius = rate at 55 degrees Celsius / rate at 25 degrees Celsius
Plugging in the values we know, we get:
9 minutes / t minutes = 27 / 1
Simplifying this proportion, we get:
27t = 9
Dividing both sides by 27, we get:
t = 1/3
Therefore, the time it takes to react at a temperature of 55 degrees Celsius is 1/3 of a minute, or 20 seconds.
