Ammonium bromide is a crystalline solid that decomposes endothermically when heated: NH₄Br(s)⇌ NH₃(g)+ HBr(g).When solid NH₄Br is added to an evacuated flask at 300°C,which change in reaction conditions below will cause the equilibrium to shift to the right?

Question

Decreasing the pressure shifts the equilibrium to the side with more gas molecules, according to Le Chatelier's principle. In this case, it shifts to the right, producing more NH3(g) and HBr(g).
