The system at equilibrium below is heated. How does the system adjust to reestablish equilibrium? 2SO(g) + O(g) 2SO3(g) + 198 kJ A. The reaction will not change because it was already at equilibrium. B. The reaction will shift toward the reactants (left) and increase the concentration of SO. C. The reaction will shift toward the products (right) and increase the concentrations of SO, and O. D. The reaction will shift toward the reactants (left) and increase the concentrations of SO, and O
