Chapter 9, Problem 9.112SP

Interpretation Introduction

Interpretation:

The value of $\Delta$ H^o in kilojoule for the given reaction needs to be determined.

${\text{CaCO}}_{\text{3}}\left(\text{s}\right)\to \text{CaO }\left(\text{s}\right){\text{ + CO}}_{\text{2}}\left(\text{g}\right)\text{?}$

Concept introduction:

Internal energy (U) is defined as the energy contained within the system. This energy can be transformed to heat and work done in the system. It is a state function, which means independent of the path taken and depends only on the initial and final states.

Enthalpy (H) of the system measures the energy in the system. It is defined by the following equation:

$\Delta$ H = U + W
