Question

The densities of graphite and diamond at 298 K are 2.25 and 3.31 g cm^-3, respectively. If the standard free energy difference (ΔG°) is equal to 1895 J mol^-1, the pressure at which graphite will be transformed into diamond at 298 K is 

(a) 9.92 x 10⁸ Pa 

(b) 9.92 x 10⁷Pa 

(c) 9.92 x 10⁶Pa 

(d) 9.92 x 10⁵Pa

Answer 1

The correct option is: None

Explanation:

ΔG = -PΔV = Work done
