I have a 96 acura t.l that wont start up anymore?

I looked at the engine and noticed that belt #3 was missing see image. http://www.google.com/m/search?site=images&gl=us&client=ms-android-hms-tmobile-us&source=mog&hl=en&aq=f&oq=&aqi=-k0d0t0&fkt=3684&fsdt=7016&cqt=&rst=&htf=&his=&maction=&q=belts+in+a+1996+acura+t.l+engine#i=13. Whats the name of that belt and is that the reason my cat wont start. Thanks!
