Im very new at Latex so I might be asking something trivial, so apologies if that is the case.
I have been trying to find an arrow for a chemical equation, I have attached a screenshot of the equation so you can see the arrow (scanned from a book).

It seems to me if I add the package {chemfig} and use the -U> arrow I can get the curve I need, the problem is I cannot seem to find a reversible reaction arrow, i.e. left and right arrow, with the curve on top. Is there such a symbol to make a reversible U arrow?
I would like to avoid custom designing an arrow because I have no experience of writing in tikz and it seems too much of an overkill for me to learn that to make one arrow!
Any help will be greatly appreciated, thank you in advance.
