The numbers represent the change in energy (ΔH) for a chemical reaction. Which number would result from an endothermic reaction?
Answer
A
negative 1
B
0
C
negative 212
D
800
Explanation
An endothermic reaction absorbs energy from its surroundings, so its change in enthalpy (ΔH) is positive. Of the choices, 800 is positive, so the answer is 800.
