In which reaction would the activation energy result in an endothermic reaction? water freezing an egg cooking a candle burning iron rusting

Just did the test.

Answer is "An egg cooking".

I thought it was a candle burning because it keeps going until the light goes out but was wrong :( lol.

Hope this helps!

Answer : The correct option is, An egg cooking

Explanation :

Water freezing  : It is an exothermic process. In this process, the heat is released when the phase changes from the liquid state to solid state.

An egg cooking  : It is an endothermic process. In this process, the heat is absorbed when the phase changes from the solid state to liquid state.

A candle burning : It is an exothermic process because the more amount of  heat is released when candle burns.

Iron rusting : It is an exothermic process because heat is released during the iron rusting process.

Hence, an egg cooking  is an endothermic reaction.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
