MCQ
The standard state gibbs free energy change for the given isomerization reaction 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
  • ✓
    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
✓

Answer

Correct option: A.
More cis $-2-$pentene is formed
(a) Equilibrium shifts backward by Le-chatelier’s principle.
