Textbook Question
Chapter 5, Problem 81E
Among the substances that react with oxygen and that have been considered as potential rocket fuels are diborane [ B2H6, produces B2O3(s) and H2O(g) ], methane [ CH4, produces CO2(g) and H2O(g) ], and hydrazine [ N2H2, produces N2(g) and H2O(g) ]. On the basis of the heat released by 1.00 g of each substance in its reaction with oxygen, which of these compounds offers the best possibility as a rocket fuel? The ΔH°f of B2H6(g), CH4(g), and N2H4(l) may be found in Appendix G.
