Question

Which statement correctly describes an endothermic chemical reaction?
Options
A The products have higher enthalpy than the reactants, and the ΔH is negative.
B The products have higher enthalpy than the reactants, and the ΔH is positive.
Correct Answer
C The products have lower enthalpy than the reactants, and the ΔH is negative.
D The products have lower enthalpy than the reactants, and the ΔH is positive.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Endothermic reactions absorb heat from the surroundings. The products have higher enthalpy (potential energy) than the reactants, so ΔH = H_products - H_reactants is positive.

Hint

Endo = in, heat goes in. ΔH positive.
