Consider each of the following systems at equilibrium. The temperature is kept constant, and in each case the reactants are in a cylinder fitted with a movable piston.
For which system(s) will a decrease in pressure favor the formation of products? Check all that apply.
a) A(s) ⇌ 2B(s) b) 2A(l) ⇌B(l) c) A(g) ⇌ B(s) d) 2A(g) ⇌ B(g) e) A(g) ⇌ 2B(g)
