Flask chemical reaction
WebM x Ś. Suppose a 500. mL flask is filled with 0.60 mol of H₂ and 2.0 mol of HC1. The following reaction becomes possible: H₂ (g) + Cl₂ (g) → 2HC1 (g) The equilibrium constant K for this reaction is 0.734 at the temperature of the flask. Calculate the equilibrium molarity of H₂. Round your answer to two decimal places. M x Ś.
