For which one of the following reactions, the value of ΔG increases with increase in temperature:

\(\mathrm{C}(\mathrm{~s})+\mathrm{H}_{2} \mathrm{O}(\mathrm{~g}) \longrightarrow \mathrm{CO}(\mathrm{~g})+\mathrm{H}_{2}(\mathrm{~g})\)
\(\mathrm{N}_{2}(\mathrm{~g})+3 \mathrm{H}_{2}(\mathrm{~g}) \longrightarrow 2 \mathrm{NH}_{3}(\mathrm{~g})\)
\(\mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \longrightarrow \mathrm{H}_{2} \mathrm{O}(\mathrm{~g})\)
\(\mathrm{N}_{2}(\mathrm{~g}, 20 \mathrm{~atm}) \longrightarrow \mathrm{N}_{2}(\mathrm{~g}, 1 \mathrm{~atm})\)

Answer

(A) C ( ~s )+ H _ 2 O ( ~g ) CO ( ~g )+ H _ 2 ( ~g )
