If an endothermic reaction begins at 26 degrees celsius and decreases by 2 degrees Celsius per minute, how long would it take to
Natalija [7]

Answer:

It would take 13 minutes.

Explanation:

The temperature decreases at a linear rate, meaning that we can describe the process by using the following formula:

  • T₂ = T₀ - 2*t

Where T₂ is the final temperature, T₀ is the initial temperature; and t is the elapsed time in minutes.

We input the data given by the problem:

  • 0 °C = 26 °C - 2°C/min * t

And solve for t:

  • t = 13 min
