Thermodynamics

In a one-litre flask, 6 moles of A undergoes the reaction A(g)⇌P(g). The progress of product formation at two temperatures (in Kelvin), T1 and T2, is shown in the figure:If T1=2T2 and (∆G2⊖−∆G1⊖)=RT2‌ln‌x, then the value of x is
[ ∆G1⊖ and ∆G2⊖ are standard Gibb's free energy change for the reaction at temperatures T1 and T2, respectively.]
