Thermodynamic Favorability

APCHEM-X1UFVE

It is observed that the production of calcium chloride from its elements gives an extremely high product yield with a heat of formation of -796 kJ/mol at room temperature.

Which of the following statements BEST describes the thermodynamic favorability of the reaction?

A

The reaction only occurs due to the use of a catalyst since it is endothermic and shows a decrease in entropy.

B

The reaction is spontaneous and is driven by both the enthalpy and entropy of the system.

C

The reaction is spontaneous but is driven by only the enthalpy of the system.

D

The reaction is spontaneous but is driven by only the entropy of the system.
