Δ G° =-2.303 R T log Kp Δ G° =-2.303 ×(8.314) ×(298) ( log 2.47 × 10-29) Δ G° =163000 J mol -1 =163 kJ mol -1

Q. Calculate $Δ G^{\circ}$ for conversion of oxygen to ozone, $\frac{3}{2} O_{2} (g) ⟶ O_{3} (g)$ at $298 K$ , if $K_{p}$ for this conversion is $2.47 \times 1 0^{- 29}$ .

$163 k J m o l^{- 1}$

$2.4 \times 1 0^{2} k J m o l^{- 1}$

$1.63 k J m o l^{- 1}$

$2.38 \times 1 0^{6} k J m o l^{- 1}$

$Δ G^{\circ} = - 2.303 RT lo g K_{p}$
$Δ G^{\circ} = - 2.303 \times (8.314) \times (298)$
$(lo g 2.47 \times 1 0^{- 29})$
$Δ G^{\circ} = 163000 J m o l^{- 1}$
$= 163 k J m o l^{- 1}$
