Solution

The correct option is B 10
Given-
$△_{r} H_{298 K} = - 54.07 k J m o l^{- 1}$
$△_{r} S_{298 K}^{o} = 10 J K^{- 1} m o l^{- 1}$
$R = 8.314 J K^{- 1} m o l^{- 1}$
$2.303 \times 8.314 \times 298 = 5705)$
we know-
$△ G^{o} = △ H^{o} - T △ S^{o}$
$= - 54.07 \times 10^{3} - (298) (10) J m o l^{- 1}$
$= - 57050 J m o l^{- 1}$
We know,
$△ G^{o} = - 2.303 R T l o g K^{o}$
$l o g_{10} K^{o} = \frac{△ G^{o}}{2.303 R T} = \frac{57050 J m o l^{- 1}}{5705 J m o l^{- 1}} = 10$
hence, $l o g_{10} K^{o} = 10$
