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:

A

More cis `-2-` pentene is formed

B

Equilibrium shifts in the forward direction

C

Equilibrium remains unaltered

D

More trans `-2-` pentene is produced

Text Solution

Verified by Experts

The correct Answer is:
