A chemical reaction?
The egg requires heat to be cooked. This means that in order to start the frying "reaction", a certain number of joules of heat have to be added to the frying pan, which transfers the heat to the egg. The egg solidifies as a result of the frying reaction.If frying the egg was exothermic, the egg would produceheat when fried (which would be very strange!).

An egg would be endothermic. Energy to cook the egg would be absorbed by the pan.
The chemical composition was changed during frying.

You can buy the frying pan, along with other cooking utensils, at the Junk Shop.
For the most part, "four egg frying pan" is simply an indication of the size of the pan; that being said, there is a special pan available with four indentations designed to keep the eggs separate.
If by "freeze" you mean stuck, perhaps your not using a lubricant in your frying pan. Before you put the egg in the frying pan, always melt a spoonful of butter in the frying pan first. When the butter has melted, then you may add your egg. Butter may be subsituted with margarine, olive oil, grape seed oil, etc.
I use an egg beater a great deal when cooking. An egg timer is also very useful. An electric griddle or frying pan are found in most kitchens.
