In some parts of the world, butadiene was produced from ethanol, C2H6O by the unbalanced reaction: C2H60 (g) → C4H6 (g) + H20 (g) + H2 (g) 1. Balance the above reaction. I'd like you to determine whether this reaction is exo- or endothermic, but you need more information first. The following questions will walk you through this process. 2. Given the reaction and thermochemical data below, use Hess' Law to calculate A H,xn for the gas-phase combustion of butadiene. 11 O2 (g) = ? kJ C4H6 (g) + 4 CO2 (g) + 3 H20(1) - 2 H20 (g) A H; = -484 kJ 2 H2 (g) + O2 (g) + 6 02 (9) 4 CO2 (g) + 4 H20 (g) AHxn =-2527 kJ C4H8 (g) AHixn = +132 kJ C4H8 (g) C4H6 (g) + H2 (g) AHvap = +41 kJ H20(1) H20 (g)
