I know this is for predictions but give me a break I'm mentally ill.
Ok so I need help on this equilibrium constant question: The reaction for the formation of hydrogen iodide does not go to completion but reaches an equilibrium: H2 + I2 <---> 2HI A mixture of 1.9mol H2 and 1.9mol I2 was prepared and allowed to reach equilibrium in a closed vessel on 250cm^3 capacity. The resulting equilibrium mixture was found to contain 3.0mol of HI. Calculate Kc.
