Instead of the commonly used reaction of hydrocarbons with air as a high-performance fuel, it was suggested to use diborane with air. AH°com (B2H6(g) = -2165 kJ/mol, and AH°.com (C2H6) = -1560 kJ/mol. AS B2H6 +232 J/mol·K, AS B206 = +54 J/mol-K, AS ethane = +230 J/mol.K, AS O₂ = +205 J/mol K, AS H2O +70 J/mol·K, AS CO₂= +214 J/mol.K. a. Calculate the comparative E per gram. b. Calculate change in entropy for each reaction. c. What are practical disadvantages of using diborane?
