Equilibrium Question 143
Question: The standard state gibbs free energy change for the given isomerization reaction cis-2-pentene ⇌ trans -2 -pentene is $ -3.67,kJ/mol $ at $ 400K $ . If more trans-2-pentene is added to the reaction vessel, then [CBSE PMT 1995; BHU 1999; AFMC 2000]
Options:
A) More cis -2-pentene is formed
B) Equilibrium is shifted in the forward direction
C) Equilibrium remains unaffected
D) Additional trans-2-pentene is formed
Show Answer
Answer:
Correct Answer: A
Solution:
Equilibrium shifts backward by Le-chatelier’s principle.
