VRAAG 6 Dааr wоrd 0,8 mоl wаterstоfgas en 0,8 mol koolstofdioksiedgas in ‘n 5 dm3 fles ingespuit en die reaksie bereik ewewig teen 1650 ˚C. Die gebalanseerde vergelyking vir die reaksie is: ∆H = + 41,2 kJ.mol-1 6.1 Stel Le Chatelier se Beginsel in woorde. (2) 6.2 Is hierdie reaksie endotermies of eksotermies? (1) 6.3 Hoe sal die volgende veranderinge die hoeveelheid mol CO(g) by ewewig beïnvloed? Kies uit VERHOOG, VERLAAG of BLY DIESELFDE 6.3.1 Druk verhoog (1) 6.3.2 Temperatuur verlaag (1) 6.3.3 Verduidelik jou antwoord op VRAAG 3.2 volgens Le Chatelier se Beginsel (3) 6.4 Teken ‘n eenvoudige, benoemde grafiek om die reaksietempo teen tyd vir hierdie reaksie voor te stel. (3) 6.5 Wanneer ewewig bereik word, is daar 0,55 mol CO(g) in die fles. Bereken die ewewigskonstante Kc vir die reaksie teen hierdie temperatuur. (7) [18]
