Can someone please answer the following question and in addition, name me the reactions from fastest to slowest and explain WHY things are the way they are? I got the answer when attempting it on my own but I feel it was just luck. The reason why I chose B was due to the charges making it an ionic bond but I don't know if this is WHY that answer is right. As for the other letters, I have absolutely no idea what to do with them (although the question doesn't ask for specifics, I'd like to know them please).
Based on the number and type of bonds to be broken and formed, which of the following chemical reactions would you expect to occur at the fastest rate at room temperature?
A) CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(g)
B) Ag+(aq) + F-(aq)→ AgF(s)
C) Mg(s) + 2 HCl(aq) → MgCl2(aq) + H2(g)
D) Fe(s) + S(s) → FeS(s)
Any help would be GREATLY appreciated!
Thanks in advance!
