WebJan 30, 2024 · Situation 1: Q = K When Q=K, the system is at equilibrium and there is no shift to either the left or the right. Take, for example, the reversible reaction shown below: CO ( g) + 2H2 ( g) ⇌ CH3OH ( g) The value of K c at 483 K is 14.5. If Q=14.5, the reaction is in equilibrium and will be no evolution of the reaction either forward or backwards.
