"For a dimerization reaction, 2A(g) $\to$ A2(g) at 298 K, $\Delta$Uo = –20 kJ mol–1, $\Delta$So = –30 JK–1 mol–1, then the $\Delta$Go will be _____ J."

Question

Accepted Answer

"$\Delta$G^o = $\Delta$H^o - T$\Delta$S^o

= ($\Delta$U^o + $\Delta$n_gRT) - T$\Delta$S^o

= $$\left[ {\left\{ { - 20 + \left( 1 \right){{8.314} \over {1000}} \times 298} \right\} - {{298} \over {1000}} \times \left( { - 30} \right)} \right]$$ kJ

= – 13.537572 kJ

= – 13537.57 Joule"

For a dimerization reaction,
2A(g) $\to$ A₂(g)
at 298 K, $\Delta$U^o = –20 kJ mol^–1, $\Delta$S^o = –30 JK^–1 mol^–1,
then the $\Delta$G^o will be _____ J.
