    Derive a rate law from a mechanism (rates of reactions)

    Your mechanism looks a bit confusing to me, because the elementary steps don't seem to add up to the overall equation.

    Why does helium have a greater first ionization energy than hydrogen?

    Why do you think that hydrogen atom is the largest of all, volumetrically? I would say atoms of other elements, say chlorine, would disagree with you. Back to your point, I think you are a little bit confused between the neutrality of an atom and the first ionization energy. When you consider an...

    Dissociation of HCl in Ethanol: Factors Affecting Ability

    In a textbook, HCl is said to remain as molecules in liquid ethanol. However, I still wonder whether HCl dissociates in ethanol to give H+ and Cl- ions. I think that as ethanol contains an OH group which is polar, ethanol molecules are capable of breaking the bond H-Cl in a manner similar to...

    Why Can't Wet Paper Ignite?

    Another reason I myself came up with is that vaporised water molecules surround the paper, preventing it from coming into contact with oxygen in the air. As such, combustion of paper cannot take place.

    Why is the bond length of HI longer than that of HCl?

    Why did you think that the larger atomic radius of iodine makes the bond length of HI smaller? Correct me if I'm wrong but it's pretty common sense that the larger the atomic radius, the longer the bond length. Besides, due to the smaller electronegativity of iodine, H-I bond is not as polar as...
