Consider the reaction A↔B, where Keq is 10^-3. Initial concentrations of A and B are 10^4 uM and 100 uM respectively. If, at equilibrium, you add 10^6 uM of product, what would be the outcome?
The reaction would remain at equilibrium because there would be no net change happening
The reaction would move towards making more product
The reaction would remain at equilibrium because you're just adding more reactant
The reaction would move towards making more reactant
