The standard state Gibbs's energy change...

The standard state Gibbs's energy change for the isomerisation reaction `cis-2-pentencehArrtrans-2-pentence` is `-3.67 kJ mol^(-1)` at `400 K`. If more `trans-2-pentene` is added to the reaction vessel, then:

More cis -2- pentene is formed

Equilibrium shifts in the forward direction

Equilibrium remains unaltered

More trans -2- pentene is produced
