QUESTION 5 H2 and F2 react according to the following equation, forming HF. H2 + F2 --> 2HF (AH° = -271 kJ/mol rxn) If H2(g) and F2(g) were reacted in a calorimeter, the reaction that occurred would be: O exothermic, and the water temperature in the calorimeter temperature would rise. O endothermic, and the water temperature in the calorimeter temperature would rise. O endothermic, and the water temperature in the calorimeter temperature would fall. O exothermic,...
