KLIK HIER OM VRAAG 5 TE SIEN VRAAG 5 5.1 In 'n 2 dm3 hоuer reаgeer 0,1 mоl SO2 gаs en 0,05 mоl NO2 gаs by 460oC. Die reaksie word hieronder getoon. Die stelsel is 'n geslote stelsel SO2 + NO2 ⇌ SO3 + NO 5.1.1 Skryf die K c uitdrukking vir hierdie reaksie uit. (2) 5.1.2 Bereken die ewewigskonstante by hierdie temperatuur as die mol NO(g) gevind word as 0,02mol by ewewig. (5) 5.2 Beskou die ewewig tussen die waterstofsulfaatioon en water: HSO4 – (aq) + H2O(l) ⇌ SO4 2- (aq) + H3O+ (aq) 5.2.1 Wanneer die temperatuur verlaag word, neem die pH van die oplossing af. Gebruik hierdie inligting om af te lei of die voorwaartse reaksie eksotermies of endotermies is. Verduidelik volgens Le Chatelier se beginsel. (4) 5.2.2 Bereken die konsentrasie van OH- ione in die waterige ewewigsmengsel as die konsentrasie van H3O+ ione by 25˚C, 2,5 x 10 -3 mol.dm-3 is. (3) 5.3 Beskou die reaksie in 'n geslote sisteem: H2(g) + I2(g) ⇌ 2HI(g) (
