Use $R = 8.314 J mo l^{- 1} K^{- 1}$ and $ln 10 = 2.303$ . For a reaction with $K = 1.0 \times 1 0^{3}$ at $298 K$ , $Δ G^{\circ}$ is closest to

Δ G^{\circ} = - RT ln K = - (8.314) (298) (2.303 \times 3) /1000 = - 17.1 kJ mo l^{- 1}

. Using

lo g_{10} K

instead of

ln K

would give

- 7.43

, and a positive sign is wrong because

K > 1
