. For N2(g)+3H2(g)⇌2NH3(g), at 500 K if Kp is fixed and total pressure is increased greatly, the equilibrium mole fraction

For N2(g) + 3H2(g) ⇌ 2NH3(g), if H2 is continuously removed at equilibrium, the system will A Shift to products

For 2A(g) ⇌ B(g), if volume is decreased at constant temperature, the equilibrium will shift A Toward more moles B

For a large equilibrium constant K, the reaction mixture mainly contains A Mostly reactants B Mostly products C Equal amounts

What best describes a reversible reaction at equilibrium A Both directions occur B Reaction stops fully C Forward only proceeds
