Question: For a hypothetic reaction $ A\to B $ , the activation energies for forward and backward reactions are 19 kJ/mole and 9 kJ/mole respectively. The heat of reaction is
[CBSE PMT 2000]
Options:
A) 28 kJ
B) 19 kJ
C) 10 kJ
D) 9 kJ
Show Answer
Answer:
Correct Answer: C
Solution:
$ \Delta H=E _{a} $ for forward reaction $ -E _{a} $ for backward reaction $ =19-9=10kJ $ .
