Problem: If Qc< Kc, in which direction will a reaction proceed in order to reach equilibrium?

FREE Expert Solution

We’re being asked to determine the direction of the shift of the reaction to reach equilibrium.


For this kind of problem, we use the reaction quotient, Q, to determine if the chemical reaction would be at equilibrium or not. The formula for Q is:


Q = productsreactants


Depending on if Q is greater than or less than K, our reaction will shift to attain equilibrium by reaching the equilibrium constant K:
