Which of the following relation is correct?
- A \(d G=V d p+S d T\)
- B \(d G=V d p-S d T\)
- C \(\Delta G=-R T \ln (K)\)
- D \(d U=p d V+T d S\)
Answer & Solution
Correct Answer
(B) \(d G=V d p-S d T\)
Step-by-step Solution
Detailed explanation
The Gibb's function is defined in terms of temperature \((T)\), enthalpy \((H)\), and entropy \((S)\) as G=H-T S In a thermodynamic process with no composition change, change in Gibb's energy is Using the combined first and second laws \(d U=T d S-p d V\) and \(d H=T d S+V d p\)…
