Chemical Thermodynamics Question 356
Question: Standard Gibb’s free energy change for isomerization reaction cis-2-pentene $ \rightarrow $ trans-2-pentene is $ -3.67kJ/mol $ at 400 K. If more trans-2-pentene is added to the reaction vessel, then
Options:
A) more cis-2-pentene is formed
B) equilibrium remains unaffected
C) additional trans-2-pentene is formed
D) equilibrium is shifted in forward direction
Show Answer
Answer:
Correct Answer: A
Solution:
- If more trans-2-pentene is added, then its concentration in right hand side will increase. But in order to maintain the K constant, concentration of cis-2-pentene will also increase. Therefore more cis-2- pentene will be formed.
