D) +, +, -
Correct Answer: B
Solution :
\[\underset{(\ell )}{\mathop{{{C}_{8}}{{H}_{18}}}}\,+\underset{(g)}{\mathop{\frac{25}{2}{{\text{O}}_{\text{2}}}}}\,\,\text{ }\to \,\,\underset{(g)}{\mathop{8\text{ }C{{O}_{2}}}}\,+\underset{(\ell )}{\mathop{9{{H}_{2}}O}}\,\] \[\Delta ~H=-ve\] (exothermic) \[\Delta G=-ve\] (spontaneous) \[\Delta \,S=-ve\] (gas moles \[\downarrow \])
