Early goals in either half from Nicklas Bendtner - making his first league start for Arsenal since March 2011 - and Mesut Ozil allowed the Gunners to secure maximum points for the 11th time in 14 outings so far this season.
Danish striker Bendtner made the most of a rare start when he kicked things off inside two minutes, heading home Carl Jenkinson's cross from close range.
Arsenal dominated much of the first half and could have gone further ahead on a number of occasions if it wasn't for an inspired display from Hull keeper Allan McGregor who came up with a number of vital saves.
Hull did make inroads in the final ten minutes of the opening term but all that hard work came undone two minutes after the break when the defence switched off on the left flank, thinking the ball was out of play, allowing Nacho Monreal to keep play going with a pass to Ozil.
The influential German flicked it through to partner in crime Aaron Ramsey who let his mate run into a dangerous position in the area before slipping a lovely reverse ball for Ozil to hit a first-time effort past McGregor, notching his third league goal for the north Londoners.
From there it was a matter of seeing out the result in a professional manner and Arsene Wenger would have been pleased with yet another clean sheet - their fifth in six outings - and a sixth straight home win.
