Reaction response Answer Bank Outside stress increase (reactant) decrease [reactant] increase (product) decrease (product] shift left shift right After changing the concentrations of A and B, they re-adjust but eventually stop. Why? The reaction stops once it reaches equilibrium. The forward and reverse reactions occur at the same rate, keeping the concentrations constant
