In a flask of fixed volume, 4 moles of A3(g) are mixed with 6 moles of B2(g) anc the gases react to form A2B(g) as the only product at constant temperature. Which of the following statements is true after the reaction is complete? O 2 moles of B2(g) are leftover. O As the reaction proceeds, the total pressure in the flask increases. O 4 moles of A2B(g) form. O There are 9 moles of gas present when the reaction is complete. B2(g) is the limiting reactant.
