Consider the reaction of hydrogen gas (H2) and iodine gas (I2) to form hydrogen iodide (HI) at a certain temperature. If the initial concentrations of hydrogen and iodine are [H2] = 0.5 M and [I2] = 0.3 M, and the equilibrium concentration of hydrogen iodide is [HI] = 0.1 M, what is the value of the reaction quotient (Qc) for this reaction at this temperature?
