If kp = 0.15, which statement is true of the reaction mixture before any reaction occurs?

I believe the correct statement would be: Q>K; The reaction will proceed to the left, since Qp=1, and 1 > 0.15. 
Kp is the equilibrium constant with respect to partial pressures in atmospheres. 
Kp takes the same form as Kc except  we use the partial pressure of gases instead of concentrations. To gauge the progress of a chemical reaction relative to equilibrium we use a quantity called the reaction quotient, Q which takes the same form as the equilibrium constant. 

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.
