Gibbs Free energy

What makes a reaction feasible?

ΔG must be <0

What is the Gibbs Free energy Equation?

ΔG = ΔH - (TΔS / 1000)

Where:

ΔG = Free energy change

ΔH =Enthalpy change (kJ mol^-1)

T = Temperature (K)

ΔS = Entropy change (JK^-1 mol^-1)

Define feasibility

The measure of the likelihood that a chemical reaction can occur under specific conditions, considering factors like energy, concentration, and temperature.

It assesses whether the reactants can transform into products and whether the process is thermodynamically favorable.

Name an example where a reaction has negative ΔG, however isn’t feasible

Diamond → graphite

This is due to Diamonds very high activation energy, making the reaction really slow
