Question -

Calculate $△ G^{\circ}$ for conversion of oxygen to ozone
$3 / 2 O_{2} (g) \to O_{3} (g) a t 298 K, i f K_{p}$ for this conversion is 2.47 $\times$ $10^{- 29}$
(Use log(2.47) = 0.4)

Options:

A .

163 K J m o l^{- 1}

B .

2.4 X 10^{2} K J m o l^{- 1}

C .

1.63 K J m o l^{- 1}

D .

2.38 X 10^{6} K J m o l^{- 1}

Answer: Option A
:
A

$△ G^{\circ} = - 2.303 R T l o g K_{p} = - 2.303 \times 8.314 \times 298 \times l o g (2.47 \times 10^{29}) \frac{j}{m o l} = 163 \frac{k j}{m o l}$
