FREE Expert Solution

We are being asked what would be the reaction quotient and the shift in the concentration of the reaction mixture given the concentrations of the reactants and product. 


We will use the reaction quotient, Q, to determine if a chemical reaction would be at equilibrium or not. The formula for Q is:


Q = prodcutsreactants


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