Since the heat of solution of KI is 20.3 kJ/mol, the answer to the question is a. Exothermic, ΔH is positive

There are two types of chemical reactions namely exothermic and endothermic reaction.

  • For exothermic reactions, heat is released. So, ΔH is positive
  • For endothermic reactions, heat is absorbed. So, ΔH is negative

Given the heat of solution of KI as 20.3 kJ/mol.

Since it is positive, the reaction is exothermic and  ΔH is positive

Since the heat of solution of KI is 20.3 kJ/mol, the answer to the question is a. Exothermic, ΔH is positive
