# Problem: At 500 °C, the Kp for the below reaction is 1.45 x10–5. When 75 atm N2, 35 atm H2, and 5 atm of NH3 are added to a container and heated to 500 °C, in which direction does the reaction proceed?N2(g) + 3 H2(g) ⇌ 2 NH3(g)A. The reaction proceeds to the right towards products until  Qp = KpB. The reaction proceeds to the left towards reactants until  Qp = KpC. The reaction proceeds to the right towards products until  Qp &gt; KpD. The reaction proceeds to the left towards reactants until  Qp &lt; Kp

At 500 °C, the Kp for the below reaction is 1.45 x10–5. When 75 atm N2, 35 atm H2, and 5 atm of NH3 are added to a container and heated to 500 °C, in which direction does the reaction proceed?

N2(g) + 3 H2(g) ⇌ 2 NH3(g)

A. The reaction proceeds to the right towards products until  Qp = Kp

B. The reaction proceeds to the left towards reactants until  Qp = Kp

C. The reaction proceeds to the right towards products until  Qp > Kp

D. The reaction proceeds to the left towards reactants until  Qp < Kp
