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-pentence` is added to the reaction vessel, then:

additional trans-2-pentene is formed

more cis-2-pentene is formed

equilibrium is shifted in the forward direction

equilibrium remains unaffected.

Text Solution

Verified by Experts

The correct Answer is:

More cis -pentene is formed to restore the equilibrium.
