Which condition among the following holds true at the state of half-completion for the reaction A B ?

Step-by-step solution

Equilibrium condition in the course of a reversible chemical reaction is in which no net change in the amounts of reactants and products occurs. At equilibrium, the reaction is half completed, [A]=[B] Thus, [B] [A] =1 According to standard free Gibbs energy, aligned G^ & =-R T K G^ & =-R T (1) [ G^ . & =0] aligned Hence, at equilibrium condition, the reaction is half-completed i.e., A B .
