Thermodynamics Question 69
Question: In endothermic reaction, the value of change in enthalpy $ (\Delta H) $ is
[Pb. CET 2001]
Options:
A) Positive
B) Negative
C) Zero
D) None of these
Show Answer
Answer:
Correct Answer: A
Solution:
For endothermic reaction enthalpy of products $ (H _{P}) $ > enthalpy of reactant $ (H _{R}) $
Hence, change in enthalpy, $ \Delta H=H _{P}-H _{R}= $ Positive
