For which reaction from the following, `DeltaS` will be maximum?

Options

A. `Ca(s) +(1)/(2)O_(2)(g) rarr CaO(s)`
B. `CaCO_(3)(s) rarr CaO(s) +CO_(2) (g)`
C. `C(s) +O_(2)(g) rarr CO_(2)(g)`
D. `N_(2)(g) +O_(2)(g) rarr 2NO(g)`

Explanation

To determine which reaction has the maximum change in entropy (ΔS), we need to analyze the change in the number of moles of products and reactants for each reaction. The change in entropy is related to the change in the randomness or disorder of the system, which can be quantified using the formula:

\[ \Delta n = \text{moles of products} - \text{moles of reactants} \]
