For which of the following cases, `DeltaS = (DeltaH)/(T)`?

Options

A. A process of which `DeltaC_(p) =0`, but `DeltaC_(v) = 0`
B. An isothermal process
C. An isobaric process
D. An isothermal reversible phase transition process

Explanation

To determine for which case \( \Delta S = \frac{\Delta H}{T} \), we will analyze each option step by step.

### Step 1: Analyze Option A
**Case:** Process where \( \Delta C_p = 0 \) but \( \Delta C_p \neq 0 \)

- For this case, the change in entropy \( \Delta S \) is given by the integral:
\[
\Delta S = \int \frac{dQ}{T}
