Q

Recall features of static equilibrium

A

Features of Static Equilibrium:
- Reaction only occurs in one direction → irreversible
- The forward and reverse reaction rate = 0
- Macroscopic and microscopic properties are unchanged
- Includes limiting reagents

Q

Define steady state system

A

Steady State System is a system where reactants are being added and products are being removed and to an outside observer, would be at equilibrium

Q

Relate reversibility to Gibbs free energy

A

ΔG < 0, the reaction is not reversible as the reverse reaction has ΔG > 0
