Chemistry 12: Please complete two questions please. Keg =5.0 at a certain temperature for the reaction 2.502(g)+O(g)=2.503(g). A certain amount of 503(g) was placed in a 2.0L reaction vesse ned 0.30 mol of O2(g). What concentration of SO3(g) was originally placed in the vessel? (4 marks) A reaction mixture, 2ICl(g)+H2(g)=12(g)+2HCl(g), was found to contain 0.500mol of Cl(g),0.0560 mol of H2(g), 1.360 mol of 12(g) and 0.8 a 1.00L bulb. How manv moles of c(a) would have to be removed in order to reduce the IHCl(a)l to 0.680M when eaullibrium is re-established? (4
