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 $${P^ \circ } \to 0, \Rightarrow {G^ \circ } \to \infty $$
