What is the standard Gibbs free energy for the transformation of diamond to graphite at 298 K? Cdiamond?Cgraphite Express your answer to three significant figures and include the appropriate units. Gibbs free energy is a measure of the spontaneity of a chemical reaction. It is the chemical potential for a reaction, which is minimized at equilibrium. It is defined as G=H?TS Elemental carbon usually exists in one of two forms: graphite or diamond. It is generally believed that diamonds last...

I cannot seem to figure it out.
The standard Gibbs-free energy of a system is related to its equilibrium constant through the following equation. AG = R.T.In(K) In this equation R is the gas constant, T is the temperature, and the next to AG defines the conditions as standard ambient temperature and pressure, i.e. "SATP". (Answer the following questions to three significant figures.) (a) Given an equilibrium constant of 6.28 x 10-3, what is its standard Gibbs-free energy? 4.9 12.6...
