Hydrogen iodide gas decomposes into hydrogen gas and iodine gas at 453°C. If a 2.00 L flask is filled with 0.200 mol of hydrogen iodide gas, 0.156 mol hydrogen iodide remains at equilibrium. What is the equilibrium constant, Kc. for the reaction at this temperature? 2 HI (g) ⇌ H2 (g)+ I2 (8) 0.020 0.0062
Hydrogen gas, iodine vapor, hydrogen iodine are mixed in a flask and heated to 642°C. H2(g) + I2(g) ⇋ 2 HI(g) Kc = 53 at 642°C If the initial concentrations of hydrogen gas and iodine vapor are both 0.054 mol/L and the concentration of hydrogen iodine is 0.130 mol/L what is the equilibrium concentration of hydrogen gas?

Hydrogen iodide, HI, is formed in an equilibrium reaction when gaseous hydrogen and gaseous iodine gas are heated together. First, write the equilibrium reaction and balance it. The volume of the reactor is not changing during the process. Now, if 24.2 g of H2 and 24.2 g of I2 are heated, they form 9.9 g of hydrogen iodide, what mass of hydrogen remains unreacted? No unit is needed. At least 3 sig fig is needed. Avoid too much rounding! You...
The reaction H2(g) + I2(g) → 2 HI (g) is first order in both hydrogen and iodine. It is therefore referred to as second order overall. Its rate constant for the formation of HI (g) at 400 ◦C is 2.34 × 10−2 · lit · mol−1 · sec−1 and its activation energy is 150 KJ/mol. Use the rate law to estimate how long it takes to form 0.1 mole of HI(g) if I start by putting 2 moles of H2...
