    You have to find the average activation energy
    just search or calculate?

    I've been stuck on Rg for over an hour now. Whatever the answer is, does anybody know if it has anything to do with combustion equillibrium? I just can't seem to find whatever those percentages mean. All I can think of is that it has to do with the combustion products, as oxygen, helium, and neon can't combust so they're 0%.

    Same conclusion here. Haven't got the answer

    Just finished, Rg was easier than I thought it would be, started looking at all sorts until I realised what to do!

    Each of the different shapes represent a different atoms and where two shapes touch, this represents a bond. Just draw them out with the atoms instead of the shapes

    Ok, for silver, have you worked out a general formula? The case then is to search for structural isomers of that.

    Clue
    The long ones are carbon, and they do not overlap one another in the middle bond.
    Extended Clue
    This means the central bond is a -C-O-C- bond. Find that functional group, then you should be away.


    For Rg, it's far simpler than it looks. I found the pattern by looking at the last two elements listed. Also, try entering 99.8. It's not much of a clue, but it may help.

    Thank you! Thank you! Thank you!

    After staring at the Rg and googling to no avail for 16 hours, my brain finally clicked after seeing your post. I never thought it was that simple...you're really a genius btw....

    For anybody stuck on Gold:

    Look up the Arrhenius plot.

    All you need is the data given, the reaction itself is irrelevant.

    Yeah, it did have me staring for a while. I had the incomplete value, and the actual meaning of the values for ages, I was just being rather idiotic and kept failing to realise the actual formula I needed was staring me in the face, and I was just being completely blind to it...

    I've figured out the general formula and have found some isomers but no right answer
