In a three-reaction system, the first two reactions are endothermic with AH values of AH1=101 kJ and AH2 = 358 kJ, respectively. If the final reaction is exothermic, what is the minimum value of AH3 that would make the overall reaction exothermic? Show your work and explain your reasoning very carefully.

Check the explanation

Explanation:

The total reaction when it comes to a three-reaction system can be endothermic, that is when two of the reaction is exothermic although it is very rare since the 2 exothermic reactions will have to be of smaller size combined H° than that of the endothermic reaction. If that action is absent then the reaction cannot be endothermic.

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.
