Consider the following system at equilibrium at 298K : 2NO(g)N2(g)+O2(g) If the PRESSURE of the equilibrium system is suddenly increased at constant temperature: The reaction must: A. Run in the forward direction to restablish equilibrium. W5 B. Run in the reverse direction to restablish equilibrium. C. Remain the same. Already at equilibrium. The number of moles of O2 will: A. Increase. B. Decrease. C. Remain the same
