Now, these exponents come from the coefficients X-Y-Z and W. Now, if our q is equal to our k, that means our reaction is already at equilibrium. Now, if q is greater than k at the beginning of our reaction, that means our reaction is reacting favorite. And that's because let's look at the ratio. If q is greater than k, that means the concentrations of our product c and d is greater than that in equilibrium. And that means our equilibrium will shift this way. In other words, these products will tend to convert to reactants.
