The normal boiling point of a liquid \( \mathrm{X} \) is \( 400 \mathrm{~K} \). Which of the following statement is true about the process \( \mathrm{X}(\mathrm{l}) \longrightarrow \mathrm{X}(\mathrm{g}) \) ?
(a) At \( 400 \mathrm{~K} \) and \( 1 \mathrm{~atm} \) pressure \( \Delta \mathrm{G}=0 \).
(b) At \( 400 \mathrm{~K} \) and \( 2 \mathrm{~atm} \) pressure \( \Delta \mathrm{G}=+\mathrm{ve} \).
(c) At \( 400 \mathrm{~K} \) and \( 0.1 \mathrm{~atm} \) presure \( \Delta \mathrm{G}=- \) ve.
(d) At \( 410 \mathrm{~K} \) and \( 1 \mathrm{~atm} \) pressure \( \Delta \mathrm{G}=+\mathrm{ve} \).
