Gibbs free energy of a pure fluid approaches __________ as the pressure tends to zero at constant temperature.

A. Infinity

B. Minus infinity

C. Zero

D. None of these

Answer: Option B

Solution(By Examveda Team)

We know : $$G = {G^ \circ } + RTln\frac{f}{{{P^ \circ }}}$$
$$ \Rightarrow $$ where $${G^ \circ }$$ and $${P^ \circ }$$ are at standard states
So, we can say when $${P^ \circ } \to 0, \Rightarrow {G^ \circ } \to \infty $$
