FREE Expert Solution

We are being asked to identify if the system is in equilibrium. 

We will 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:
