Question

For the chemical reaction H2 + CO2 → H2O + CO, the energy contained in the reactants is 394 kJ, and the energy contained in the products is 352 kJ, assuming 1 mol of each substance is present. Which of the following statements is true?

Answer 1

where's the following statements?

Answer 2

C. 42 kJ is absorbed, and the reaction is endothermic. Because the amount of energy in the products is less than that of the reactants, the reaction is endothermic. Endothermic reactions use up, or absorb energy.
