### 8.111 part c

Part A gives us the formula 2H2S(g)+O2(g)->2S(s)+2H2O(l) and
we know from part b of the equation that the enthalpy for 60 kg of sulfur is -4.96x10^5 kJ.

Part c asks would the reactor need to be cooled or heated to maintain a constant temperature?

Specifically, my question is what exactly is a reactor?

For chemical reactions, they're best done in a chemical reactor-- typically vessels (e.g. a tank) and you can think of reactors as the system for reactions.

Reactors are used because they help maximize the reaction's output by minimizing the extent of certain variables that could affect the efficient of product yields, etc.

In this particular problem, the given reaction is exothermic and so the reactor is emanating heat. To prevent the reactor from overheating, it would be wise to cool it.
