Question

For the change $H_{2}O\left(s\right),(273K,2atm)\to H_{2}O\left(l\right),(273K,2atm)$, choose the correct option.

• A. $\Delta G=0$
• B. $\Delta G<0$
• C. $\Delta G>0$
• D. None of these

Answer 1

The correct option is B $\Delta G<0$

$H_{2}O\left(s\right)\to H_{2}O\left(l\right)$,
At $P=1atm,\Delta G=0$, there is equilibrium at 273 K.
Hence, as $P\uparrow$, more $H_{2}O\left(l\right)$ is formed.
