Chemical Kinetics Question 205
Question: $ A\to B,\Delta H=10kJ,mo{l^{-1}},{E_{a(f)}}=50kJ,mo{l^{-1}} $ , then $ E_{a} $ of $ B\to A $ will be
Options:
A) $ 40kJ,mo{l^{-1}} $
B) $ 50kJ,mo{l^{-1}} $
C) $ -50kJ,mo{l^{-1}} $
D) $ 60kJ,mo{l^{-1}} $
Show Answer
Answer:
Correct Answer: D
Solution:
$ A\xrightarrow{{}}B,\Delta H=-10,kJ,mo{l^{-1}} $ It is an exothermic reaction. $ {E_{a(b)}}={E_{a(f)}}+\Delta H $
$ =50-(-10)=60kJ $
