Question 144

Multiple Choice

What is the entropy change if 4.500 g of CaCO3(s) is placed in a container and allowed to decompose to CaO(s) and CO2(g) according to the following reaction?
CaCO3(s) \leftrightarrow CaO(s) + CO2(g)  Substance S(J/molK) CaCO3(s) 92.88CaOO(s) 39.75CO2(g) 213.6\begin{array} { c c } \text { Substance } & \boldsymbol { S } ^ { \circ } ( \mathbf { J } / \mathbf { m o l } \cdot \mathbf { K } ) \\\mathrm { CaCO } _ { 3 } ( s ) & 92.88 \\\mathrm { CaOO } ( s ) & 39.75 \\\mathrm { CO } _ { 2 } ( g ) & 213.6\end{array}
