Question
What factors must you consider to determine the sign of $\Delta S$ for the reaction: $2 \mathrm{HI}(g) \longrightarrow \mathrm{H}_{2}(g)+\mathrm{I}_{2}(g) ?$
Step 1
In this case, we have 2 moles of HI(g) reacting to form 1 mole of H2(g) and 1 mole of I2(g). This means that the total number of moles of gas is the same on both sides of the reaction. Show more…

What factors must you consider to determine the sign of $\Delta S$ for the reaction $2 \mathrm{~N}_{2} \mathrm{O}(g) \longrightarrow 2 \mathrm{~N}_{2}(g)+\mathrm{O}_{2}(g)$ if it occurs at constant temperature?
Describe two ways that you could determine $\Delta G^{\circ}$ of a reaction.
For the reaction. $2 \mathrm{Cl}(\mathrm{g}) \rightarrow \mathrm{Cl}_{2} \mathrm{~g} \mathrm{~g}$, what are the signs of $\Delta \mathrm{H}$ and $\Delta \mathrm{S}$ ?
