The aim of the game is to make the highest yield of C by adding feeds A and B into this batch reactor. Be careful not to overfill the reactor! As the reaction occurs, heat is given out and the temperature increases. If the reactor temperature and pressure get too high, the reactor can explode and the run is over.
You can control the feeds in, the steam (to heat feed A), the cooling water flow (to cool the reactor) and the stirrer speed by adjusting the up and down arrows.
The difficulty of the game depends upon the rate of reaction and the heat of
reaction. In the easy choice, reaction rate and heat are low, in the medium these
parameters are limited, but in the hard case, the reaction proceeds rapidly with
much heat generated. Take Care!

Many chemical substances give out heat when they react together. These reactions are known as exothermic. One of the most obvious examples is combustion when fuel burns (is oxidised) in air. The fuel could be a gas (eg natural gas), a liquid (eg petrol), or a solid (eg coal or wood).
Other examples of exothermic processes include neutralisation (reacting an acid with a base), polymerisation (converting a monomer such as ethylene into polyethylene) and nuclear decay.
Control of an exothermic reaction is difficult as reaction rates increase exponentially as the temperature rises. If the heat cannot be removed by cooling, the reaction can 'run away' causing safety issues with excess temperature or pressure. A dramatic example can be seen by following Runaway: Explosion at T2 Laboratories.
In 2011 there was a major disaster at the Fukushima Daiichi nuclear power plant in Japan when the tsunami damaged the cooling system and the reactors over heated. See Wikipedia.
