A catalyst decreases the activation energy and increases reaction rate that is needed.
The first colorimeter (i'm guessing is standard) is less exact then the actual reading, and has a harder time pin-pointing. (it gives a number near the actual temperature, but it is not correct.)
The second colorimeter is exact, and should be 'trusted more in the future', because it gives an accurate reading of the current temperature.
