Question

What will be change in entropy for the decomposition of $C a C O_{3}$ ?

Open in App

Solution

Decomposition of $C a C O_{3} \to$
${C a C O_{3}}_{(s)} ⟶ {C a O}_{(s)} + {C O_{2}}_{(g)}$
The entropy of the above reaction is increasing because a gas is being produced and the number of molecules is increased.
