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
Correct Answer: Minus infinity
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 $${P^ \circ } \to 0, \Rightarrow {G^ \circ } \to \infty $$
