Question
Assuming gasoline is pure $\mathrm{C}_{8} \mathrm{H}_{1 \mathrm{~s}}(l)$, predict the signs of $q$ and $w$ for the process of combusting gasoline into $\mathrm{CO}_{2}(g)$ and $\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) .$
Step 1
Combustion of gasoline (octane) is an exothermic reaction, which means it releases heat to the surroundings. Therefore, the heat transfer (q) is negative (q < 0). Show more…
