The standard state Gibb's free energy change for the isomerisation reaction cis-2-pentene $ightleftharpoons$ trans-2-pentene is $-3.67 \mathrm{~kJ} \mathrm{~mol}^{-1}$ at $400 \mathrm{~K}$. If more trans-2-pentene is added to the reaction vessel
  1. more cis-2-pentene is formed
  2. equilibrium shifts in the forward direction
  3. equilibrium remains unaltered
  4. more trans-2-pentene is produced

Solution

Equilibrium shifted in the backward direction. (Le Chatelier's principle) *
