Hello.
Answer: -55. When adding two negatives, you add like you would any positive number.
-4b - 2c =
(-4 × 2.5) - (2 × 3)
-10 - 6
= -16
So, -4b - 2c = -16
Hope this helps and let me know if anymore help is needed!!

The activation energy is the amount of energy required to initiate a certain reaction. The activation energy may considered as an "energy barrier" that has to be overcome in order for a reaction to begin. If a reaction has a lower activation energy, then it will occur more easily and at a faster rate than a reaction with a higher activation energy. Therefore, the reason that reaction 1 is faster than reaction 2 is because it has a lower activation energy than reaction 2.
