Consider this reaction equation: A2B(g)= 2 A(g) + B(g) If you start with 1.2 M A2B, and if at equilibrium, 50% of it has decomposed, what are the equilibrium concentrations of A and B? What is the value of the equilibrium constan

Suppose a 250. mL flask is filled with 0.40 mol of H₂ and 1.3 mol of HI. This reaction becomes possible: H₂(g) +1₂(g) → 2HI(g) Complete the table below, so that it lists the initial molarity of each compound, the change in molarity of each compound due to the reaction, and the equilibrium molarity of each compound after the reaction has come to equilibrium. Use x to stand for the unknown change in the molarity of H₂. You can leave out the M symbol for molarity. initial cha equilibrium H₂ 0 X 0 1₂ 0 HI 00 믐 X olo 18 Ar

0.186 mol/L of A₂(g) and 0.186 B₂(g) are initially present in a flask. The A2 and B₂ react according to the balanced equation below. A₂(g) + B₂(g) = 2 AB(g) When equilibrium is reached, the concentration of B₂(g) has decreased by 0.036 mol/L. What is the equilibrium constant, K, for the reaction?

Suppose a 250. mL flask is filled with 0.60 mol of N₂ and 0.40 mol of O₂. The following reaction becomes possible: N₂(g) + O₂(g) → 2NO(g) The equilibrium constant K for this reaction is 9.69 at the temperature of the flask. Calculate the equilibrium molarity of N₂. Round your answer to two decimal places. X
