    Part A: If we start with 0.500 moles of H2 (subscript) and 0.500 moles of I2 (subscript) in a 5.25 L reaction vessel at 698 K, how many moles of each of the three gases will be present at equilibrium?

    Equation:
    H2(subscript) + I2(subscript) <--> 2HI

    KEQ= 54.3 at 698 K

    Part B: The same set up as part A, but this time start with 0.800 moles of H2 (subscript).
