Is the following process exothermic or endothermic? Select the single best answer.→CaCO3s + CaOs CO2g =ΔH+42.5kcal
Question
Is the following process exothermic or endothermic? Select the single best answer.→CaCO3s + CaOs CO2g =ΔH+42.5kcal
Solution
The process is endothermic. This is because the ΔH (change in enthalpy) is positive (+42.5kcal), which indicates that the reaction absorbs heat from its surroundings. In an endothermic reaction, the energy of the products is higher than the energy of the reactants.
