Chapter 5, Problem 4KSP

Using only whole-number coefficients, the combustion of hexane can be represented as:

$\begin{array}{l}{\text{2C}}_{\text{6}}{\text{H}}_{\text{14}}\left(l\right){\text{ + 19O}}_{\text{2}}\left(g\right)\to {\text{12CO}}_{\text{2}}\left(g\right){\text{ + I4H}}_{\text{2}}\text{O}\left(l\right)\hfill \\ \Delta H_{}^{\text{o}}\text{ = 8388}\text{.4kJ/mol}\hfill \end{array}$

Using this and data from Appendix 2, determine the standard enthalpy of formation of hexane.

$\begin{array}{l}\left(\text{a}\right)\hfill \\ \text{-334}\text{.8 kJ/mol}\hfill \\ \left(\text{b}\right)\hfill \\ \text{-167}\text{.4 kJ/mol}\hfill \\ \left(\text{c}\right)\hfill \\ \text{-669}\text{.6 kJ/mol}\hfill \\ \left(\text{d}\right)\hfill \\ \text{+334}\text{.8 kJ/mol}\hfill \\ \left(\text{e}\right)\hfill \\ \text{+669}\text{.6 kJ/mol}\hfill \end{array}$
