Question

For the chemical reaction H2+CO2----> H2O+COthe energy contained in the reactants is 352 kJ, and the energy contained in the products is 394 kJ.

Assuming 1 mol of each substance is present. How much energy is either absorbed or released during the reaction?


42 kJ is absorbed, and the reaction is endothermic.

42 kJ is released, and the reaction is endothermic.

42 kJ is released, and the reaction is exothermic.

42 kJ is absorbed, and the reaction is exothermic.

Answer 1

Answer:

42 kJ is released and the reaction is exothermic

Explanation:

because this reaction liberates Energy while forming a product
