The table shows the thermodynamic data for a reaction. Thermodynamic Data Energy of the Reactants Energy of the Products Activat
NNADVOKAT [17]

Answer:

The change in enthalpy is +210 kJ, so it is an endothermic reaction.

Explanation:

  • The change in enthalpy shows that the reaction is exothermic or endothermic.

The change in enthalpy = The energy of products - the energy of reactants.

  • If ΔH is positive value, the reaction is endothermic, the energy of the products is higher than that of the reactants.
  • If ΔH is negative value, the reaction is exothermic, the energy of the products is lower than that of the reactants.

<em>For this reaction: </em>The change in enthalpy = The energy of products - the energy of reactants = 370 kJ - 160 kJ = + 210 kJ.

<em>So, the right choice is: The change in enthalpy is +210 kJ, so it is an endothermic reaction.</em>
