This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement-I : The standard free energy changes of all spontaneously occuring reactions are negative. Statement-II : The standard free energies of the elements in their standard states at 1 bar and 298 K are taken as zero.

Enthalpy, entropy and free energy of formation of elementary substances in the standard state are taken as zero.

Statement-1: Combustion of all organic compounds is an exothermic reaction . Statement-2: The enthalpy of formation of all elements in their standard state are zero.

The standard free energy change DeltaG^(@) is related to k (equilibrium constant) as
