Vedclass · Answer

(B) In an endothermic process,heat is absorbed from the surroundings by the system. According to the first law of thermodynamics,the change in enthalpy $\Delta H$ is defined as the heat exchanged at constant pressure. Since heat is absorbed,the enthalpy of the products is greater than the enthalpy of the reactants $(H_{products} > H_{reactants})$. Therefore,$\Delta H = H_{products} - H_{reactants} > 0$. Thus,for an endothermic process,$\Delta H$ is positive.

For an endothermic process,$\Delta H$ will be ...... .
