A Reaction Vessel Is Cold to the Touch and the Reaction

question 49

Multiple Choice

A reaction vessel is cold to the touch and the reaction results in an increase in order of the products inside the reaction vessel. Which statement correctly confirms whether or not the reaction is spontaneous and explains why?

• A)The reaction is exothermic (-\(\Delta\)H)as demonstrated by the cold reaction vessel and entropy is increased (+\(\Delta\)S). The reaction has a negative \(\Delta\)G and is, therefore, spontaneous.
• B)The reaction is endothermic (+\(\Delta\)H)as demonstrated by the cold reaction vessel and entropy is decreased (-\(\Delta\)S). The reaction therefore has a positive \(\Delta\)G and is, therefore nonspontaneous.
• C)The reaction is exothermic (+\(\Delta\)H)as demonstrated by the cold reaction vessel and entropy is increased (-\(\Delta\)S). The reaction has a positive \(\Delta\)G and is, therefore, spontaneous.
• D)The reaction is endothermic (-\(\Delta\)H)as demonstrated by the cold reaction vessel and entropy is increased (+\(\Delta\)S). The reaction has a positive \(\Delta\)G and is, therefore, nonspontaneous.
