Equilibrium Ques 27
27. Standard Gibb’s free energy change for isomerization reaction
[1995]
cis- $2$ - pentene $\rightleftharpoons$ trans-$2$-pentene
is $-3.67$ $ kJ / mol$ at $400$ $ K$. If more trans-$2$-pentene is added to the reaction vessel, then
(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

Answer:
Correct Answer: 27.(a)
Solution:
- (a) 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.
