Question
Two different proteins X and Y are dissolved in aqueous solution at 37 C. The proteins bind in a 1:1 ratio to form XY. A solution that is initially 1.00 mM in each protein is allowed to reach equilibrium. At equilibrium, 0.18 mM of free X and 0.18 mM of free Y remain. What is Kc for the reaction?Explanation / Answer
When X and Y react X + Y --> XY equilibrium means rate of forward reaction is equal to backward So when 0.18 of reactant is left it means rest is gone to product and the mechanism of formation is now stable. Hence it is not necessary to have molar 1:1 ratio in reactant and product but its important to match both rates
