The equilibrium constant for reaction is 10. What will be the value of ΔG o (R=8.314JK −1 mol −1 & T=300K)

Relation between Kp and Kc:

When concentration are expressed in terms of mole fractions.

We know that partial pressure (P) = Mole fraction × Total pressure (Pt)

In Homogeneous gaseous equilibrium, M(g) + 3N(g)--> 4P(g). Initial concentration of M is equal to that of N. If equilibrium concentrations of M and P are equal then what will be the value of KC?
