The equilibrium constant K_c for this reaction is 0.16 at 25 °C, and the standard enthalpy change is 16.1 kJ.

Predict the effect of each of these changes on the position of the equilibrium; that is, state which way the equilibrium will shift (left, right, or no change) when each of these changes is made for a constant-volume system.

(a) Adding more Br₂

(b) Removing some NOBr

(c) Lowering the temperature
