The reaction that would result in decreased entropy is : ( A ) CO(s) → CO2(g)
What are Endothermic reactions
Reactions that absorb heat from its surroundings are known as endothermic reactions, Endothermic reactions result in a decreased entropy as the temperature of the surrounding becomes lower than the temperature of the container where the reaction occurs.
Examples of endothermic reactions are : melting and evaporation which results in the change of state from solid to liquid or from solid to gaseous state.
Hence we can conclude that The reaction that would result in decreased entropy is : ( A ) CO(s) → CO2(g)
