Problem 1. Calculate AH for the following equation and state whether or not the nature of the reaction is endothermic or exothermic (Note: You will find Table 3-2 in your textbook helpful for solving this problem. Also, note that AH; for MnO:(aq) = -518.4 kJ/mole, and that S(s) is the standard state for sulfur at 25°C and 1 atm). 2 MnO, (aq) + 5 H₂S(g) + 6 H-(aq)→ 2 Mn¹(aq) + 5 S(s)+ 8 H₂O(1)
