For the formation of hydrogen iodide, H2(g) + 12(g) - 2HI(g) the value of the equilibrium constant at 700K is 54.7. If one mole of H2 and one mole of 12 are the
only materials initially present, what will be the equilibrium concentrations of H2,
12, and HI.

Nitric oxide (no) can be formed from nitrogen, hydrogen and oxygen in two steps. in the first step, nitrogen and hydrogen react to form ammonia: n2(g) + 2 h_2(g) rightarrow 2 nh_3 (g) delta h = -92. kj in the second step, ammonia and oxygen react to form nitric oxide and water: 4 nh_3(g) + 5 o_2(g) rightarrow 4no(g) + 6 h_2o(g) delta h = -905. kj calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
