Which of the following is affected by the temperature?

A. Fugacity

B. Activity co-efficient

C. Free energy

D. All of the above

Answer: Option D

Solution(By Examveda Team)

All the three will be effected by temperature and the relation between the temperature and fugacity is given by : \[{\left( {\frac{{\partial ln{f_i}}}{{\partial T}}} \right)_{P,n}} = \frac{{ - \overline {{H_l}} + {{\overline {{H_l}} }^{^ \circ }}}}{{R{T^2}}}\]
Activity co-efficient and temperature given by : \[\frac{{\partial lna}}{{\partial {T_P}}} = \frac{{{H^{^ \circ }} - H}}{{R{T^2}}}\]
Free energy and temperature is given by : \[{\left( {\frac{{\partial G}}{{\partial T}}} \right)_P} = S\]
