Which of the following statements is true of an endothermic reaction? I. Heat is absorbed from the surrounding II. The heat content of the products is more than that of the reactants III. The enthalpy change is positive IV. The surrounding is at a lower temperature than the system.
For an endothermic reaction; heat flows from the surroundings to the system( but that doesn't make the surroundings to be at a lower temperature than the system) meaning the surroundings are at a higher temperature than the system. The system's enthalpy change, i.e. ΔH is positive or > 0. The heat content of the product is more than that of the reactant.
