- For the reaction 4HCl(g) +O2(g) == 2Cl2(g) + H2O (g), Keq =889 at 480 o If 0.03 mole HCl , 0,02 mole O2 , 0.08 mole Cl2 and 0.07 mole H2O were mixed in 1 liter container, in what direction will the reaction proceed. Support your answer.I this calculation of the enthalpy of a reaction as measured in a constant pressure telemetry container, I totally get everything except for the exothermic part. I understand that hcl at 25 C mixed with NaOH at 25 degrees gives off h20 and heat, thus exothermic. But what puzzles me is why the formula q = s m delta T yields a positive number indicating an endothermic process. ( final temp higher than initial)For the reaction A + B <=> AB, kassoc = 2.0 sec-1 M-1 and kdissoc = 0.5 sec-1. This means that Kassoc is equal to ____ M-1.
