• # question_answer Given that $dE=TdS-pdV$ and $H=E+pV$. Which one of the following relations is true? A)  $dH=TdS-Vdp$ B)  $dH=SdT+Vdp$ C)  $dH=-SdT-Vdp$   D)  $dH=dE-pdV$

Given,                 $dE=TdS-pdV$ ... (i)                 $H=E+pV$ ... (ii) Differentiating Eq. (ii)                 $dH=dE+pdV+Vdp$ ... (iii) From Eq.,(i) and (iii), we get $dH=TdS-Vdp$
