• Write a balanced equation for the reaction.
• Explain what feature is shown by the arrow labeled (a).
• Using chemical symbols and dashed lines (this can be done with type), draw what the activated complex or transition state might look like.
• Is this reaction exothermic or endothermic? Explain.

Balanced equation:  2 HgO (s) - > 2 Hg (l) + O2 (g)

gebooors · Answer

Reaction needs energy because energy of products is higher that energy of 
Reactants, that' how you find out is reaction exo- or endothermic
