Answer:
The reaction must be spontaneous, the disorder of the system increases.
Explanation:
By the Second Law of Thermodynamics, a positive change in entropy is due to a net input heat, and entropy is a measure of the grade of disorder within the system. The net input heat means that resultant goes to the system from the surroundings.
By the First Law of Thermodynamics, a net input heat is due to a positive change in enthalpy.
The reaction is endothermic and spontaneous (since change in entropy is positive).
