The equilibrium concentrations of the species in the reaction A + B...

$A + B ⇔ C + Datequilibrium23106$

${K}_{eq} = \dfrac{[ C ] [ D ]}{[ A ] [ B ]}{K}_{eq} = \dfrac{10 \times 6}{2 \times 3} = 10 ∆ G º = – RTlnK$

Where $R$ is the gas constant,$T$is the temperature in Kelvin, and $K$ is the equilibrium constant of the reaction.

$\Delta G = - 2 . 303 \times 2 \times 300 \times \log_{10}10 = - 2 . 303 \times 2 \times 300 \times 1 = - 1381 . 8cal$
