use Matlab and write out the code. or I will give you a thumbs down and report you

Problem 2. An exothermic, relatively slow reaction takes place in a reactor under your supervision. Last night, after you left the plant, the temperature of the reactor went out of control, for a yet unknown reason, until the operator put it under control by changing the cooling water flow rate. Your supervisor has asked you to prepare a report regarding this incident. As the first step, you must figure out when the reactor reached its maximum temperature and what was the value of this maximum temperature. A computer was recording the temperature of the reactor at one-hour intervals. Plot the measured temperature versus time and cubic splines through the measured temperature. Find the value of the maximum temperature and the corresponding time with two decimal places
