Which compound will undergo dehydration more readily?

My guess would be the second one will undergo dehydration with ease relative to the first one although I am not sure. One reason that comes to my mind is that the carbocation formed in the first one will be destabilized by the ketone. Is my guess correct? If yes, am I correct in my reasoning too? Or are there any other dimensions that I am missing to look into.


Any help would be appreciated.
