okay we say that reaction is spontaneous if [tex]\Delta G \le 0[/tex](adsbygoogle = window.adsbygoogle || []).push({});

consider a rxn at equilibrium

A + B [tex]\rightleftharpoons[/tex] C + D

for forward rxn be spontaneous i.e [tex]\Delta G \le 0[/tex]

then by rule backward rxn will be non spontaneous

then WHY at equilibrium backward rxn taking place
