Expert Solution
Step 1

16a. Endothermic reactions are those reaction in which heat is absorbed from the surroundings. In an endothermic reaction, the energy of products is higher than energy of reactants which results in a positive value of enthalpy of a reaction i.e ΔHo>0

Hence, option c) is correct answer.
