Equilibrium - Result Question 31
####33. Standard Gibb’s free energy change for isomerization reaction
[1995]
cis- 2 - pentene $\rightarrow$ 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
Show Answer
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.
