The chemical potential of component 1 in a solution of binary mixture is $\mu_{1}=\mu_{1}^{0}+\mathrm{RT} \ln \mathrm{p}_{1}$, when $\mathrm{p}_{1}$ is the partial pressure of component 1 vapour phase. The standard state $\mu_{1}^{0}$ is:
(a)Independent of temperature and pressure
(b)Depends on temperature and pressure both
(c)Depends on temperature only
(d)Depends on pressure only
Answer
Answer: C ✓ checked by 4AB · confidence high
Explanation
μ₁° is the chemical potential at unit partial pressure; it depends on temperature only (the pressure is fixed by the standard-state definition).
