In a reversible process

A. Tds = dE + dW

B. DE - dW = Tds

C. DW - dE = Tds

D. Tds - dW + dE >0

Answer: Option A

Solution(By Examveda Team)

From second law of thermodynamics :
$$\eqalign{ & TdS \geqslant \delta Q \cr & \Rightarrow TdS \geqslant dU + \delta W \cr} $$
For an irreversible process $$TdS - dU - \delta W > 0$$
And for an reversible process $$TdS - dU - \delta W = 0$$
