Final answer:
When hydrogen gas is removed from the reaction 2H2S ⇌ 2H2(g) + S2(g), equilibrium shifts to the right to produce more hydrogen gas according to Le Châtelier's principle.
Step-by-step explanation:
When considering the equilibrium for the reaction 2H2S ⇌ 2H2(g) + S2(g), removing hydrogen (H2) gas would result in the equilibrium shifting to produce more of the removed component. According to Le Châtelier's principle, if a product is removed from the system, the equilibrium will shift to the right to produce more product to counteract the change. Therefore, the correct answer is:
A. Equilibrium shifts right to produce more product.
