Question
If a chemical reaction is carried out in a fuel cell, the maximum amount of useful work that can be obtained is (a) $\Delta G ;$ (b) $\Delta H ;$ (c) $\Delta G / \Delta H ;$ (d) $T \Delta S$.
Step 1
This is given by the equation: \[\Delta G = \Delta H - T\Delta S\] where $\Delta H$ is the change in enthalpy (heat energy), $T$ is the absolute temperature and $\Delta S$ is the change in entropy (disorder). Show more…

If a chemical reaction is carried out in a fuel cell, the maximum amount of useful work that can be obtained is (a) $\Delta_{\mathrm{r}} G ;$ (b) $\Delta_{\mathrm{r}} H ;$ (c) $\Delta_{\mathrm{r}} G / \Delta_{\mathrm{r}} H ;$ (d) $T \Delta_{\mathrm{r}} S$
Only one of the following quantities is equal to the heat of a chemical reaction, regardless of how the reaction is carried out. Which one and why? (a) $q_{V} ;$ (b) $q_{P}$ (c) $\Delta U-w ;$ (d) $\Delta U ;$ (e) $\Delta_{\mathrm{r}} H$
For most chemical reactions A. ΔH is much larger than ΔE B. ΔE is much larger than ΔH C. ΔH is equal to ΔE D. the difference between ΔH and ΔE is very small.
