Hi there, I'm new to the forums so pardon me if i make mistakes such as posting to the proper forum. 1. The problem statement, all variables and given/known data I need to investigate and analyze conditions needed to maximize the efficiency of common natural or industrial reactions and explain how the improved efficiency of the reaction contributes to the sustainability of the environment. I need to make a poster showing the ff components: conditions/ catalyst which maximize the efficiency of the reaction, explanation on how the catalyst/ condition contribute to the efficiency of the reaction and analysis of the function/s condition/catalyst in their contributory role in the sustainability of the environment. I'm not asking someone to do the poster for me (thats insane ;D). I'm just wondering if someone could help me and guide me on what industrial or natural chem rxns can be used and easily defended in other factors like explaining its role in efficiency etc. 2. Relevant equations N/A 3. The attempt at a solution looked at petroleum and its conversion to fuels( alkanes etc), looked at polymerization of ethene.
