Question #7-1 Paper 1 Difficulty: Medium

The Haber process can be represented by the equation: ${N}_2(g) + 3{H}_2(g) \leftrightarrow 2{N}{H}_3(g)$

What will the effect be on the position of equilibrium and the Kc value if the pressure is decreased on the reaction vessel?

A. Kc decreases and equilibrium shifts to the left.
B. Kc increases and equilibrium shifts to the left.
C. Kc is unchanged but equilibrium shifts to the right.
D. Kc is unchanged but equilibrium shifts to the left.
